Abstract
This paper endeavours to design a proportional-integral-derivative (PID) controller based on the use of single z-copy current follower transconductance amplifier (ZC-CFTA). The developed PID controller consists of one ZC-CFTA, two truly grounded passive components and virtually grounded passive components. It does not require any passive component matching, and the realized controller parameters are adjustable electronically. The effects of parasitic elements and tracking errors of the ZC-CFTA are also investigated. Simulation results in PSPICE demonstrate the workability of the proposed PID controller.
