Abstract
A CMOS opamp that can drive large capacitive loads is presented. The technique employs a positive feedback compensation (PFC) to improve frequency response as compared to nested Miller compensation (NMC), allowing the circuit to occupy less silicon area and straightforward design. At 1.5 V, the circuit dissipates 275 μW, has more than 100 dB gain, a gain bandwidth of 2.7 MHz and 1.0 V/μs average slew rate while driving a 130 pF load.
