Power-Aware Design Method for Class-A Switched-Current Wave Filters

Power-Aware Design Method for Class-A Switched-Current Wave Filters
Power-Aware Design Method for Class-A Switched-Current Wave Filters
This paper addresses power consumption in switched-current filters, designed using the wave filter technique and Class-A memory cells. It has been demonstrated that power consumption can be reduced through the proposed two stage bias and signal current scaling method, whilst ensuring no degradation in the filters total harmonic distortion. Two full transistor-level filter case studies using 0.6mm 3.3V BSim3v3 CMOS foundry models are given to demonstrate the method, with additional simulation results for filters of different types and orders showing power savings as high as 16.6%. One case study has been fabricated, with measured silicon results confirming power savings using the proposed method.

Abstract

This paper addresses power consumption in switched-current filters, designed using the wave filter technique and Class-A memory cells. It has been demonstrated that power consumption can be reduced through the proposed two stage bias and signal current scaling method, whilst ensuring no degradation in the filters total harmonic distortion. Two full transistor-level filter case studies using 0.6mm 3.3V BSim3v3 CMOS foundry models are given to demonstrate the method, with additional simulation results for filters of different types and orders showing power savings as high as 16.6%. One case study has been fabricated, with measured silicon results confirming power savings using the proposed method.
