This paper deals with RC active biquad working in the current mode (CM).The design approach uses only three transconductors (OTA) with the minimum necessary number of outputs and with only three passive grounded elements. Proposed filter has simple circuit configuration providing all standard transfer functions such as high-pass (HP), band-pass (BP), low-pass (LP), band-reject (BR) and all-pass (AP). Electronic tuning and independent adjusting of the quality factor and bandwidth of the band-pass filter are possible. The presented circuits are verified by PSpice simulations utilizing OTAs on transistor level of abstraction. The effects of the real active elements in suggested circuit are briefly discussed. Experimental verification is also given. Designed networks can be used in many applications such as anti-aliasing filter, in high-speed data telecommunication systems, for signal processing in cable modems, in regulation and measurement techniques etc.
