Comparative Analysis of Operational Transconductance Amplifiers (OTA) for Biomedical Applications

A common analogue processing unit is the operational transconductance amplifier (OTA). Most recently, applications in biology have benefited from the producing of OTA with exceptionally low power, low voltage, low connectivity and high accuracy. The present investigation reviews the interaction amongst the use of energy and the reliability of CMOS OTA practices for medical or low frequency purposes, as indicated in a number of literature publications. Considerations for OTA comparison includes a linear manner, technological advances, supply voltage, power consumption, frequency, and how they are utilized in the processing of biomedical signals. Future researchers will benefit from this text as they work to improve OTA for low frequency, linearity, and biological applications.
