Low voltage high performance FGMOS based Wilson current mirror

摘要

This paper presents floating gate MOS (FGMOS) based Wilson current mirror (WCM) with both low input and output voltage requirements, along with high output impedance. The bandwidth of the proposed FGMOS based WCM is 257.904 MHz and it is further increased to 316.228 MHz by using resistive compensation technique of bandwidth extension. From low-frequency small signal analysis it has been shown that the output impedance of the proposed current mirror is higher than that of conventional one. A low voltage current mode full wave rectifier (FWR) is designed by using proposed FGMOS based WCM. The simulations are performed using SPICE and TSMC 0.18 μm CMOS technology parameters with ± 0.75 V supply voltage to validate the effectiveness of the proposed circuit.
