A new four-CC-based configuration for realizing a voltage-mode biquad filter
A new voltage-mode (VM) biquad filter is presented, which employs four Current Conveyors (CC) along with five resistors and only two grounded capacitors, facilitates electronic control of filter parameters through grounded resistors (realizable by FETs/MOSFETs) and is suitable for IC implementation in bipolar or CMOS technology. The circuit offers several advantages over the four-CC-based VM biquads published earlier. The workability of the new circuit has been confirmed by PSPICE simulations.
