Abstract
Objectives: This paper carries out robustness study on p-channel and n-channel input differential amplifier (which is also known as single-stage operational transconductance amplifier). Methods and Analysis: The impact of Process, Voltage and Temperature (PVT) variations on the design metrics of both differential amplifiers is studied and suitable conclusions are drawn. Findings: The n-channel input differential amplifier is found to be more robust than p-channel input differential amplifier. Moreover, it provides higher gain, and 3-dB bandwidth as compared to its p-channel counterpart. All the results were obtained from extensive simulation using Virtuoso Analog Design Environment of Cadence @ 45-nm technology node. Application: Operational Transconductance Amplifier (OTA) can be used in the design of simple amplifiers with voltage-controllable gain and to the design of first-order and second-order active filters with controllable gains and controllable critical frequencies.
