A fully differential class AB two-stage op-amp with and without common-mode feedback circuit (CMFB) are proposed. There are 4 schematics to be proposed. The first schematic is CMOS complementary input ...

A 12 bit 50 MS/s 1.8 V pipelined CMOS analog-to-digital converter (ADC) based on a fully differential class-AB switched operational amplifier achieves low power consumption with a differential input ...
