Abstract
A chopper stabilized amplifier with recycling current is presented. The proposed chopper stabilized amplifier with current recycling has the benefit of reducing power consumption, which the chopper stabilization increases. The proposed chopper stabilized amplifier was designed in UMC standard 180nm CMOS process. Simulation results show that this chopper stabilized amplifier achieves 20.1MHz GBW, 57.5nV/sqrt(Hz) input referred noise and 1.6mHz 1/f noise corner frequency. Compared with the conventional chopper stabilized amplifier, the power consumption reduced by 50%.
