The objective of this paper is to present a new universal current-mode biquad capable of providing all the five basic filter functions, namely, low pass (LP), band pass (BP), high pass (HP), band reject (BR) and all pass (AP) from the same configuration using only three Z copy current follower transconductance amplifiers (ZC-CFTA) along with the provision of independent electronic tunability of the filter parameters 0 and Q0 (or bandwidth) through two separate DC bias currents while employing… CONTINUE READING
