Bilal Arif, Mohd. Usama Ismail, Ale Imran . A Versatile Digitally Programmable Voltage Mode Multifunctional Biquadratic Filter. International Journal of Computer Applications. 94, 15 ( May 2014), 7-13. DOI=10.5120/16417-5057
In this paper, a digitally controlled single input multi-output voltage mode multifunctional biquadratic filter is presented. The circuit makes use of only a single DVCC, two grounded capacitors, one grounded and two floating resistors. The digital control is incorporated using a current-summing network (CSN). Tuning of cut-off frequency is carried out with the help of a 3–bit digital control word. PSPICE simulations using TSMC 0. 25 micron CMOS technology have been performed to validate the theoretically predicted results.
