A new floating gate MOS (FGMOS) universal current conveyor (UCCII) is proposed to have the properties of simplifier circuit topology, simpler signal processing and wider input swing. Since the FGMOS transistors are used in the proposed UCCII circuit, the number of transistors is reduced and the topology of the circuit is simplified because it is easier to get arithmetic operations in circuits by using FGMOS transistors when compared to conventional MOS transistors. At the same time, using FGMOS differential amplifier structure in the input stage of the IGMOS UCCII circuit increased the input signal swing resulting both an increase in the linearity of the circuit and an improvement in the voltage following properties. A single input multi output (SIMO) type universal filter application is given to show the versatility of the UCCII block. Both the proposed FGMOS UCCII circuit and filter circuit are simulated with SPICE program by using 0.35 mu m technology parameters. When the simulation results are analyzed it is seen that that the FGMOS UCCII circuit reached the expected improvements according to the MOS equivalent circuit and expected to be used in linearly tunable filters.
