A high DC-gain low-power current recycling amplifier in deep sub-micron technology

چکیده
A high DC-gain low-power current recycling amplifier using positive-feedback technique is presented. In the proposed amplifier, the positive-feedback signal used to enhance the DC-gain is derived from the extra nodes created by cascoding. Positive-feedback offers the ability of obtaining a very high DC-gain, ideally infinite gain, without affecting high frequency performance and stability. Under the SMIC standard 65 nm process, the proposed amplifier was implemented. Simulation results show that the DC-gain of 104.5 dB is achieved with only power consumption of 25.5μA and the bandwidth is not limited.
