Abstract

In this paper we show how a simple Current-Starved Pseudo Floating-Gate (CSPFG) inverter can be used to realize bi-directional Circuits. The direction of the signal through the inverter is reversed (the input becomes output and vise versa) by swapping vdd and gnd, without adding any extra amplifier or circuitry. This is possible because of the symmetry of the CSPFG inverters. We use the bi-directionality property of the inverter to realize a bi-directional CSPFG Differentiator/integrator. Typical applications are in filter design and IO ports in ICs. Linearity and AC simulations are presented to show the good properties and versatility suited for Bi-directional analog circuit design.
