| Abstract: | A new current-mode universal filter with
single input and three outputs employing two second-generation current
conveyors (CCIIs), one current follower (CF) and four grounded/virtually
grounded passive elements is presented. The proposed circuit enjoys the
following features: simultaneous realization of lowpass(LP), bandpass(BP), and
highpass(HP) filtering responses, no need of matching conditions, employment of
grounded resistors which are ideal for IC implementation, employment of
grounded/virtually grounded capacitors, orthogonal control of ω0 and
ω0 / Q, high output
impedance suiting cascadibility for higher order filters, and low passive
sensitivity. PSPICE simulation results are included, confirming the workability
of the proposed circuit. |
