Abstract
An operational amplifier includes three transconductance stages (TSs) each having a differential input and a differential output, a first and second resistor coupled between the differential output of the first TS and the differential input of the first TS, a third and fourth resistor coupled between the differential output of the third TS and the differential input of the first TS, a first and second capacitor coupled between the differential output of the third TS and the differential input of the third TS, wherein the first, second, and third TSs each include a differential input amplifier coupled to the differential input of the respective TS, a differential output amplifier coupled to the differential output of the respective TS, and a plurality of Schottky diodes coupled between the differential input amplifier and the differential output amplifier for voltage level shifting.
