Design and analysis of high gain CMOS transconductance amplifier for low frequency application

Abstract

An operational transconductance-amplifier (OTA) is mainly designed for low voltage and low frequency applications such as for the medical applications. The Operational Transconductance Amplifier (OTA) is the part in an analog integrated circuits for many wireless applications such as binural hearing aids. High gain is becoming more important in miniature devices because this parametric form provide the significant outcomes, so it becomes a challenge to design a low power OTA. The proposed design helps to generates the design parameters such as the Width/Length ratio are given to design specifications, such as, gain, unity gain-bandwidth, phase margin. This paper is mainly proposed for the low frequency application using transconductance amplifier.
