摘要：

A DC gain enhanced recycling folded cascode amplifier with a new positive feedback output stage is presented. The proposed amplifier using positive feedback to cancel the output conductance allows DC gain to be enhanced without affecting the bandwidth of the amplifier. The proposed amplifier was implemented in SMIC standard 65 nm CMOS process. Simulation results show that a DC gain enhancement of 35 dB is achieved without limiting the bandwidth.
