DVCCTA based PID controller with grounded passive elements

This paper presents a Proportional Integral Derivative controller based on Differential Voltage Current Conveyor Transconductance Amplifier as an active element. In the proposed circuit, the PID parameters namely, Proportional gain constant, Integral time constant and Derivative time constant can be tuned electronically by varying the bias current of the circuit. All the passive elements used are grounded, making it suitable for on-chip implementation. This circuit can be utilized to realize PI and PD controller. The simulations are done in OrCAD PSPICE with 0.5 µm CMOS MIETEC technology.
