A FG-MOS Based Fully Differential Current Controlled Conveyor and Its Applications

This paper presents a new fully differential second generation current controlled conveyor (FDCCCII) based on differential pair topology, which employs floating gate MOS transistors (FG-MOS). It uses floating gate MOSFETs at the input stage and has rail-to-rail structure which performs with both positive and negative signals. This circuit has tunable parasitic resistance at its input port. It operates with low supply voltage (±0.8 V), low power consumption (lower than 3 mW at current bias of 1 mA), and wide range parasitic resistance (RX). This circuit has less MOSFET than the previous similar circuits and is suitable for integrated circuit design. To demonstrate the application of the proposed circuit, a fully differential current mode LC-ladder filter and a fully differential multifunction biquad filter are designed. Simulation results by HSPICE confirm validity of the proposed circuit and its application.
