Analysis of Noise in Current Mirrors with memristive Device

TL;DR

This paper analyzes noise in cascode current mirrors incorporating memristive devices, showing that memristors reduce high-frequency noise compared to basic current mirrors through simulation-based THD analysis.

Contribution

It provides a comparative analysis of noise in CMOS-memristive and basic current mirrors, highlighting the noise reduction effect of memristors at high frequencies.

Findings

Memristors decrease noise significantly at high frequencies.

Channel length change affects both circuits similarly.

AC and DC analyses are performed for balanced and unbalanced mirrors.

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, memristor in a circuit decreases noise significantly at high frequencies.
