Abstract
An efficient single-stage Folded Cascode operational transconductance amplifier (FC OTA) which features class AB operation is presented. It consumes 32.5% less power and 45.8% increase in gain as compared to two stage conventional OTA. Performance parameters of FC OTA is evaluated in 180nm technology using Cadence. As an application of OTA, Second order active filter structure for low pass, high pass and band pass filtering action is designed using the FC OTA. These filters can be used in various applications such as audio processing, image processing etc.
