Abstract

This paper presents how to add flexibility to reduce the overall power consumption in a CMOS operational amplifier by replacing few MOS transistors with floating gate MOSFET (FGMOS). The disadvantages of doing this are also discussed. The performance of the proposed circuit using unity gain bandwidth (GBW) and slew rate (SR) as figure of merit is presented. The Nested Miller compensation (NMC) is used and the pole is positioned far away from first pole in frequency spectrum for frequency compensation resulting. The zero from RC network is also matched to the non-dominant pole at the left-side of the Nyquist plot of the loop to increase stability and control the bandwidth operation. The circuit operates with a voltage supply of 0.5V and has 26.7uW power consumption.
