Single-stage fully recycling folded cascode OTA for switched-capacitor circuits

The operational transconductance amplifier (OTA) is a basic building block used in many analogue and mixed-mode circuits such as analogue-to-digital (A D) converters and switched-capacitor filters that require fast settling and precise amplifiers [1]. Recently. the folded cascode (FC) amplifier has gained preference over the telescopic owing to the low …
