Design of a 50nW, 0.5VDD sub-threshold OTA amplifier with indirect compensation technique and class AB output stage

We present analysis and design of a 0.5VDD two stage OTA amplifier with current-buffer compensation and class AB output stage in 90nm CMOS technology. All transistors in the amplifier operate in the sub-threshold region while achieving 86dB DC gain and unity gain frequency 40.5kHz with a load capacitor of 30pF. The total power dissipation is 50nW with bias current of 10nA.
