For many applications, Proportional-Integral-Derivative (PID) controllers are the optimum choice and will simply outperform almost any other control option. This is why they are currently used in over 95% of closed-loop processes worldwide. PID is a feedback mechanism that calculates the error value between the measured process variable and the desired set-point. (Guillermo, J.C. 2011) It is composed of three control parameters – Kp, Ki, and Kd – which regulate the output by determining the error, minimizing the error and stabilizing the output. This paper describes one application of the PID controller and implementing it using 0.35æ CMOS technology. The PID controller design aims to manipulate the output of a type of a step-down dc-to-dc converter to a great value using Ziegler-Nichols’ first tuning method.
