Voltage-mode PID controller using DDCCs and all-grounded passive components

Abstract

This paper presents a new voltage-mode proportional-integral-derivative (PID) controller using the differential difference current conveyors as active elements. The proposed PID controller uses all-grounded passive components which is highly suitable for integrated circuit implementation. The proportional gain, the integral time constant and the derivative time constant parameters can be independently controlled. For controlling the PID controller parameters, the circuit dose not need passive component-matching condition. The PSPICE simulation results are used to confirm the characteristics of the proposed PID controller.
