Analysis of Noise in Current Mirrors with memristive Device

Abstract

This work presents an analysis of noise in a cascode current mirror with CMOS-memristive device done by comparison with the basic current mirror. The analysis is completed based on THD for different frequency and channel length values by means of computer-aided design. AC and DC analyses are presented for both balanced and unbalanced current mirrors. While the change in the channel length has similar effect in both circuits, at high frequencies the memristive circuit is less susceptible to noise.
