An electronically fine-tunable multi-inputsingle-output universal filter

Abstract

A new electronically fine-tunable multi-inputsingle-output (MISO) universal filter is proposed. The filter circuit compared with active-device-based counterparts is very simple and fully integrable. Moreover, a few number of active transistors provide a reduction in power consumption, and the filter enjoys advantages such as no component matching and small size area. Postlayout simulation results using parameters of AMS CMOS 0.35- µ process technology show good agreement with theoretical expectations. © 2011 IEEE.
