Abstract

A universal active biquad based on the dual‐output second‐generation current‐conveyor (CCII±) is presented. The circuit uses only six CCII± and can, simultaneously, support three mixed‐mode transfer functions and five current‐mode transfer functions. The circuit uses grounded resistors and capacitors and enjoys independent grounded‐element control of the filter parameters.
