Low Power High Performance Current Mirror – A Review

Abstract

In VLSI technology the circuit has small size. The efficient size gained due to decreasing chip design to nano-scale. But as chip size becomes very less the factor which adversely affects the design is maintaining constant current in CMOS integrated circuit. Current mirror replicates input current at the output. There is need to design current mirror circuit such that it works efficiently with low power requirement. In this work the survey of different CM circuits analysed and studies. Each CM has its advantages, limitations and research gap which is noted and applicable for further development.

Performance Analysis of Gate All Around TFETs for Low Power Circuits

“…The TCAD tool Silvaco Atlas has been used to carry out of the numerical evaluations for the given device. The model used for simulation are Concentration-dependent mobility model, Shockley-Read-Hall recombination model, Band gap narrowing model, Field dependent mobility model, Auger recombination model, and Kane's band to band tunneling model [10].…”
