A novel CMOS operational amplifier with a 1.5 V power supply is presented. It is based on a folded-mirror transconductance amplifier and a high-efficiency output stage. The amplifier achieves an ...

In this paper, design challenges of an operational amplifier (opamp) for medium-resolution pipelined Analog-to-Digital Converters (ADCs) in deep-submicron CMOS processes are discussed. Comparisons are ...
