ABSTRACT
This paper presents a single Operational transresistance (OTRA) based voltage-mode proportional-derivative (PD) controller with independent tuning of proportional (Kp) and derivative (Kd) constants. This configuration can be made fully integrated by implementing the resistors using matched transistors operating in linear region.In order to verify the proposed circuit a closed loop control system using the proposed PD controller is designed and simulated using SPICE.
