  • A compact three-stage low-voltage low-power BiCMOS operational amplifier with inverted nested Miller compensation
  • Published at:IEEE MELECON’98
  • This paper presents a three-stage, compact and power-effecient 3 V BiCMOS operational Amplifier (OpAmp) with rail-to-rail input and output stages. The opamp is designed to be loaded a 20-pF capacitive load and the unity-gain bandwidth is 5.2 MHz at 62 degrees phase margin. The bipolar output stage is designed to swing an output load current of -12 to 12 mA. The opamp have an open-loop voltage gain of 122dB and a bandwidth to supply ratio of 6.42 MHz/mW for the 20pF capacitive load
