Reconfigurable 1st order filters based on differential voltage input and a single current output transconductance multiplier

Abstract

This paper deals with reconnection-less electronically reconfigurable filtering applications of the differential voltage input and single current output transconductance multiplier. A voltage-mode and mixed-mode filter solutions are presented and their electronically configurable features (change of transfer type and adjustment) are verified by simulations in a Cadence Spectre simulator with I2T100 0.7 μm technology.
