- This paper presents a current controlled current-mode single input three output (SITO) biquad universal filter employing current conveyor trans-conductance amplifiers (CCTAs) as active element. It consists of two CCTAs, two grounded capacitors and three grounded resistors. The proposed filter simultaneously realizes low pass (LP), band pass (BP) and band reject (BR) in current-mode at high impedance outputs. It can also realize high pass (HP) and all pass (AP) filtering functions with interconnection of relevant output currents. In addition, the quality factor and bandwidth can be controlled independently of pole frequency through single bias current. The circuit possesses low active and passive sensitivity performance. The validity of proposed filter is verified through PSPICE simulations.
