Versatile Active Biquad Based on Dual-Output Second-GenerationCurrent Conveyors

摘要

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, supportthree mixed-mode transfer functions and five current-mode transfer functions. Thecircuit uses grounded resistors and capacitors and enjoys independent grounded-elementcontrol of the filter parameters.
