Abstract
This research was to design a 2.4 GHz class E Power Amplifier (PA) for health care, with 0.18um Semiconductor Manufacturing International Corporation CMOS technology by using Cadence software. And also RF switch was designed at cadence software with power Jazz 180nm SOI process. The ultimate goal for such application is to reach high performance and low cost, and between high performance and low power consumption design. This paper introduces the design of a 2.4GHz class E power amplifier and RF switch design. PA consists of cascade stage with negative capacitance. This power amplifier can transmit 16dBm output power to a 50{\Omega} load. The performance of the power amplifier and switch meet the specification requirements of the desired.
Highlights
Wireless Sensor Networks (WSN) can be widely applied to solve a vast array of problems, under varied conditions[1]
Due to current hardware components restrictions, healthcare application of WSNs are still in the early stages[19][20][21][22]. Such devices require Food and Drug Administration (FDA) approval, which can be challenging and costly due to the requirement that the devices pass a number of safety tests
The cascode circuit with negative capacitance is shown in the figure 2
Summary
Wireless Sensor Networks (WSN) can be widely applied to solve a vast array of problems, under varied conditions[1]. Due to current hardware components restrictions, healthcare application of WSNs are still in the early stages[19][20][21][22] Such devices require Food and Drug Administration (FDA) approval, which can be challenging and costly due to the requirement that the devices pass a number of safety tests. Applications is that - designs a cost effective device which would meet functional requirements [2][27][28][29]. Each device must provide long working cycles without battery recharging This pushes most sensor node designs to be super ultra-low power. In order to meet the standards, the PA and RF switch are designed as shown in table 1
