A fully differential low-power operational amplifier in 0.12 μm digital CMOS technology achieving a differential gain of 80 dB is presented. A transit frequency of 20.5 MHz at ±0.7 V supply and with a load of 10 pF has been measured. Owing to an innovative bulk controller for the input transistors, the common-mode input range is larger than ±0.2 V. The operational amplifier can be used down to a supply voltage of ±0.4 V with a differential gain of 63.5 dB.
