Abstract :
In this paper, a new current-mode (CM) Kerwin-Huelsman-Newcomb ( KHN) biquad is proposed which is suitable for crossover networks. The proposed circuit employs three differential voltage current conveyors (DVCCs) as active elements together with two capacitors and four resistors as passive elements, which all are grounded. The circuit simultaneously provides the three basic filter functions, namely band pass (BP), high pass (HP) and low pass (LP) functions. TSPICE simulations are performed on employing CMOS Technology 2mum process and the performance simulation results is tested by comparing with the theoretical results of the filter.
