A Novel Very High Performance CMOS Current Mirror with extremely low input and ultra high output resistance

Abstract

In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high accuracy (error = 0.003%). The circuit has a very simple compact architecture and uses a single 1V power supply. The qualitative performance of the circuit is validated with HSPICE simulations using HSPICE TSMC 0.18μm CMOS technology.
