Excel Methods to Design and Validate in Microelectronics (Complementary Metal–Oxide–Semiconductor, CMOS) for Biomedical Instrumentation Application

CMOS microelectronics design has evolved tremendously during the last two decades. The evolution of CMOS devices to short channel designs where the feature size is below 1000 nm brings a great deal of uncertainty in the way the microelectronics design cycle is completed. After the conceptual idea, developing a thinking model to understand the operation of the device requires a good “ballpark” evaluation of transistor sizes, decision making, and assumptions to fulfill the specifications. This design process has iterations to meet specifications that exceed in number of the available degrees of freedom to maneuver the design. Once the thinking model is developed, the simulation validation follows to test if the design has a good possibility of delivering a successful prototype. If the simulation provides a good match between specifications and results, then the layout is developed. This paper shows a useful open science strategy, using the Excel software, to develop CMOS microelectronics hand calculations to verify a design, before performing the computer simulation and layout of CMOS analog integrated circuits. The full methodology is described to develop designs of passive components, as well as CMOS amplifiers. The methods are used in teaching CMOS microelectronics to students of electronic engineering with industrial partner participation. This paper describes an exhaustive example of a low-voltage operational transconductance amplifier (OTA) design which is used to design an instrumentation amplifier. Finally, a test is performed using this instrumentation amplifier to implement a front-end signal conditioning device for CMOS-MEMS biomedical applications.

Students’ academic language-related challenges in English Medium Instruction: The role of English proficiency and language gain

This article reports a quantitative empirical study that explored the relationship between English language proficiency and academic language-related challenges experienced by students when studying through English Medium Instruction (EMI). Questionnaire data using the EMI Challenges Scale and student English language test score data were collected at a public university in Turkey. Two academic subjects were compared: International Relations (a Social Science subject, n = 99) and Electronic Engineering (a Mathematics, Physical and Life Sciences subject, n = 99). Results revealed that in both subjects, English language proficiency statistically significantly predicted academic language-related challenges. Furthermore, a gain in English proficiency significantly predicted the challenges in International Relations but not in Electronic Engineering. Finally, Electronic Engineering students experienced significantly different levels of linguistic-related challenges in each language skill when at a lower proficiency (A2) compared to a higher proficiency (B2). In International Relations, a proficiency threshold was more evident; students experienced significantly higher levels of linguistic-related challenges as proficiency decreased. Important pedagogical implications of this established relationship between language proficiency, language gain, and language-related challenges in two academic divisions are discussed.

Academic Procrastination and the Stress of University Students of Electronic Engineering from the Callao Region

The results of machine learning indicate that the consultation of the videos before the class, resolution of the exercises during the class through the Quartus software and realization of the laboratory practices after the class positively influence the development of skills on circuit design. Data science identifies 3 predictive models of the use of flipped classroom through the decision tree technique. Finally, teachers can improve the learning process, develop the skills of students, build new educational spaces and carry out creative activities through flipped classroom.

WITHDRAWN: Problem-oriented and project-based learning (Popbl) as an innovative learning strategy for sustainable development in engineering education

Abstract Each and every student is a unique individual who desires a caring and inspiring atmosphere in which to develop intellectually, mentally, and socially. My vision as an educator is to pass on quality education by adopting a novel teaching–learning practice and to contribute to the betterment of society by adopting good certified practices for economic and technological development. As a teacher, my motto is to direct and provide contact to information rather than acting as the main source of information. In our institution, we aim at providing complete value based education to meet the requirements of society. To develop the skills in my students I make them engage in learning by giving them the background of the subjects, its need, and application in the real world. Currently, I am dealing with Antenna and Wave propagation subject for the 3rd year Electronics and Communication Engineering students who have most of the times worked with circuits, software’s, and design devises, etc., without knowing the internal design details and its techniques. This course gives them a clear idea about the communication techniques and also how Antenna plays a vital role in the transmission and receiving process.

A feasibility study of sensor and transducer trainers as a learning media towards electronics engineering’s students

This research aimed at determining the feasibility of sensor and transducer trainer as a learning media applied for Electronics Engineering students of FT UNM. This study’s feasibility indicators were divided into 3, namely feasible in terms of material, media, and responses from the students as users of these media trainers. The method applied in this research was Research and Development (R&D) by developing a sensor and transducer trainer. The data analysis technique used was descriptive statistical analysis. A questionnaire was used to collect the data by targeting 4 lecturers as media and material experts, while 27 students participated as a respondent. The assessment results from the material expert validator were obtained an average value of the feasibility percentage of 97%, while the assessment of the media expert received an average value of 96%. Based on this assessment, the media trainer was worthy of both the material’s content and its performance. Meanwhile, the value of students’ responses towards the use of trainers after being tested reached 84% with a very good category. The feasibility test results generally showed that the trainer could be used in practical learning of sensor and transducer course. This trainer could be developed with the addition of IoT (Internet of Things) technology to perform remote monitoring and control systems.

Supporting Team Based Learning Using Electronic Laboratory Notebooks: Perspectives From Transnational Students

Today's engineering industries require graduates with a broad range of soft skills, which include teamwork, communication and integrity. Therefore, more accreditation bodies now recommend team-learning activities to be embedded in their engineering programmes. However, hardworking students often find group projects demotivating, especially if their contributions are not accurately reflected in their individual grades. To address these issues, we demonstrate that Electronic Laboratory Notebooks can be used to promote student collaboration and teamwork on a group project. They can also help instructors assess student contributions fairly. During our investigations, we noticed that students have used Electronic Laboratory Notebooks as social interaction tools that enable text, data, images and recorded audio to be exchanged. Consequently, we describe the experiences of 58 transnational undergraduate students in using six different software products for a team-based learning activity. According to our investigations, Electronic Laboratory Notebooks had a positive impact on supporting Team Based Learning in a new electronic engineering course. The outcomes of our investigations can help create effective teaching and learning resources for undergraduate students in Electronic Engineering. They can also help staff members make evidence-based decisions regarding the introduction of Electronic Laboratory Notebooks in undergraduate research activities.

Remote Knowledge Acquisition and Assessment During the COVID-19 Pandemic

On 16 March 2020, as a result of the unprecedented global health crisis linked to the emergence of a new form of coronavirus (COVID-19), the 74 universities of France closed their doors, forcing nearly 1.6 million students, as well as their teachers, to find solutions and initiatives that could ensure continuity in teaching. In the reliance on videoconferencing tools, chat, the sharing of documents/tutorials/videos/podcasts, and the use of social networks, many ideas have emerged, but no consensus has developed nor has a common way of doing things been adopted by a majority of teachers. Some software tools, such as Zoom, have also been questioned over data security issues or excessive intrusion into the student learning process. Nevertheless, in these uncertain times, much had to be done so that students can acquire the requisite knowledge, develop skills, and build on what they have learned. How can we ensure that the learning process is as smooth as possible for everyone involved? How can we evaluate knowledge and skills learned at a distance, and their relevance? Four groups of electronic and electrical engineering students in France were monitored during the containment period in order to provide answers to these questions. Lectures, tutorials, practical work, and projects were carried out using the Microsoft Teams and Zoom video conferencing and chat tools to complement activities made available through the digital work environment. In order to ensure equity among all students, especially in view of the digital divide, open access tools/software/applications have been promoted. In the various surveys completed, the engineering students asserted their complete satisfaction with the learning process, the use of distance tools, and the level of mastery of these tools by their teachers. The results of the various knowledge tests show that, for the same course, distance learning does not reduce the performance of the engineering students. Indeed, they obtained local grades similar to those expected in face-to-face teaching. The results presented in this article are not intended to highlight the virtues of distance education, but rather to open up a debate and reflect more widely on the sustainability of this transformation of education in universities.
