| 摘 要： | A scheme of inductive wireless receiver circuit is put forward, according to special requirement of inductive wireless power supply in artificial subretinal prosthesis circuit. The proposed receiver circuit can be divided into CMOS rectifier, regulator and self-biasing circuit. The CMOS rectifier is used to provide power supply for regulator and self-biasing circuit. The self-biasing circuit furnishes the regulator with bias voltage and bias current which is independent from power supply. The proposed receiver circuit is designed by Cadence tool and Chartered 0.35 μm CMOS device model, and oscillator in artificial subretinal chip is used as the proposed receiver circuit’s load. The results show that the proposed receiver circuit can provide load capacity of 3.3 V and >1 mA,with a layout size of 62 μm×195 μm.
