A Low Noise Low Power OTA for Biomedical Applications Sunita, M S. 2018-2019 PES University Bengaluru The biomedical industry today demands low lower and low noise amplifiers. An Operational Transconductance Amplifier (OTA) is used to achieve the requirements. The project work is divided into three phases:- ? Implementation of OTA in [1] The OTA in [1] which is implemented consists of three sub circuits, namely, main amplifier, bias circuit and Common Mode Feedback Circuit (CMFB). It is a low power high gain amplifier achieving a high Common Mode Rejection Ratio (CMRR) and high Power Supply Rejection Ratio (PSRR). Simulation on 180nm technology on Cadence Virtuoso for a supply voltage of 2V; gives a static power dissipation of 325.24nW, gain of 33.87dB, CMRR of 82.88dB, PSRR of 73.86dB while maintaining a bandwidth of (1- 230)Hz. ? Modification to OTA in [1] The OTA in [1] is modified to achieve a lower static power dissipation and a higher CMRR. Adaptive biasing and CMRR improvement circuit are added to the OTA to improve static power dissipation and CMRR respectively.
