In this paper we present pseudo floating gate and its bidirectional property. Inverter also can be implemented using bidirectional property. The inverter can be made bidirectional simply by interchanging vdd and gnd and no need to add any circuitry or any amplifier. We are using this inverter to implement the differentiator and integrator. We are first implementing inverter using pseudo floating gate. The bidirectionality of the gate is further evolved to be able to control signal flow conditions. And finally using this inverter we are implementing differentiator and integrator. A bidirectional PFG gate is designed which is used to implement different bidirectional PFG amplifiers that includes single to differential amplifier, differential to differential amplifier, high gain differential amplifier, differential to single ended amplifier. The PFG inverter enables design of analog multifunctional, multi-directional circuits. 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.
