Abstract
In this paper, a digitally reconfigurable Multi Input Single Output (MISO) voltage mode multifunctional biquadratic analog filter has been presented. The circuit has three input terminals and one output terminal. It employs two Differential Voltage Current Conveyor blocks (DVCC), two capacitors and two resistors. Filter responses like low-pass, band-pass, high-pass and band-reject can be obtained from the same topology by applying voltages to different input terminals. The digital re-configurability is obtained using a current-summing network (CSN). Cut-off frequency of the various filter responses is controlled and varied with the help of a 3–bit digital control word. Further quality factor is also controlled with the 3-bit control word. PSPICE simulations using TSMC 0.25μCMOS technology have been performed to validate the theoretically predicted results.
