A power-efficient high GBW operational amplifier with its analog baseband IC implementation in 40-nm CMOS technology

This paper presented a power-efficient, relatively high voltage gain, high GBW (gain-bandwidth-product) operational amplifier (OPAMP) with a pole cancellation technique and adaptive common-mode (CM) bias circuit. A typical two-stage topology is adopted in the OPAMP prototype design while the 1st amp...
