New Universal Current Mode Biquad Employing All Grounded Passive Components But Only Two DOCCs
Raj Senani

Previously known fixed-topology type current-mode universal biquads capable of realising all the five generic filter functions while employing all grounded passive elements and providing current outputs explicitly, require at least three single/dual/multiple output Current Conveyors (CC). This paper introduces a new configuration which, by contrast, requires only two dual output CCs (DOCC) to realize the above kind of biquad. SPICE simulation results of a CMOS-based implementation have confirmed the workability of the new configuration.
