摘要：
The objective of this paper is to present a new universal current-mode biquad capable of providing all the Jive 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 notability of the filter parameters omega(0) and Q(0) (or bandwidth) through two separate DC bias currents while employing both grounded capacitors as desirable for integrated circuit implementation. The workability of the proposed structure is verified by PSPICE simulations based on CMOS implementation of the ZC-CFTA.
