CMOS VM/CM Tow–Thomas-Equivalent Biquad Filters and a Linear VCO Using Recently Proposed CMOS Transconductors

Abstract

The main objective of this paper is to present novel applications of two recently proposed CMOS transconductors in realizing voltage mode/current mode Tow–Thomas (TT)-equivalent biquads and a linear voltage-controlled oscillator (VCO), all exhibiting a number of advantages over the previously known circuits to realize the same functions. The workability of all the propositions has been demonstrated by SPICE simulation results using TSMC [Formula: see text] CMOS technology parameters.
