ABSTRACT This paper presents a new Multiple Input Single Output (MISO) Universal Filter (UF) using only two Bulk-Driven Second Generation Current Conveyors (BDCCII), three resistors and two capacitors. The proposed filter with four inputs and one output can produce all biquadratic filtering functions, namely: Low-Pass (LP), High-Pass (HP), Band-Pass (BP), All-Pass (AP) and Notch (NH) at the output terminal by selecting an appropriate input signal combination. Apart from its design simplicity, the circuit exhibits many attractive features i.e. an very-low supply voltage levels, minimum component count, low active and passive sensitivities, tuning facility of Centre-frequency (fo) and Quality factor (Q). To verify the performance of the proposed circuit PSPICE simulations have been carried out using TSMC 0.18 µm standard CMOS technology.
