Abstract (english): In this work a programmable folded cascode railto-rail operational amplifier (OpAmp) with small settling time and transconductance feedback circuit is proposed. It employs a 130 nm CMOS technology with 1.2 V power supply. The small settling time is required to charge an ADC within a given time frame. The OpAmp achieves a gain bandwidth of 19.95 MHz with a 70 pF load and a minimum settling time of 144 ns while consuming 0.551 mA quiescent current. It can be shown that with 130 nm technology, high performance amplifiers can be realized on very small area.
