Abstract

A 1.5-V square-root domain (SRD) first-order filter possessing multiple operating points is presented. The basic building blocks of the filter are based on MOS translinear loops and dynamic level shifter techniques, allowing low voltage operation and an extended dynamic range. However the dynamic level shifters introduce positive feedback inducing three operating points to the filter through a negative differential resistance. A detailed analysis of such performance employing a bi-port analysis is offered. Simulation and measurement results are provided in order to demonstrate the analysis and circuits proposed
