Abstract

In this paper is proposed a novel atto-ampere current mirror (AACM) which reaches the minimum yet reported current range of 0.4aA. Operation of this circuit is based on source voltage modulation instead of conventionally used gate voltage modulation which interestingly prevents usage of commonly required voltage shifting in those circuits. The proposed circuit has a simple structure prohibiting large chip area consumption. The proposed current mirror is the best choice for ultra low power low voltage (ULPVL) applications. Simulation results in TSMC 0.18Â¿m CMOS technology with Hspice are presented to demonstrate the validation of the proposed current mirror.
