Abstract

In this paper, a study in terms of gain, unity gain frequency of operational transconductance amplifiers (OTAs) using feedforward technique with FDCM has been carried out. OTA having feedforward technique with FDCM shows gain of 68 dB at 1 nA bias current and 10 KHz - 1GHz unity gain frequency characteristics. The input bias current from 1 nA to 1 mA has been varied for study. The CMOS OTA has been simulated in 0. 5 ?m technology with 2. 5 V power supply voltage.
