Abstract :
Proportional Integral Differentiator (PID) is widely used in industrial control applications; Digital PID is complicated and consists of many stages. This paper introduces the design of an analog PID controller by using single active element and implemented in 0.18μm CMOS technology. PID is tested by using three structures: Two stage Operational Amplifier with common source buffer stage; Folded cascade Operational Transconductance Amplifier and with a second generation Current Conveyer CCII+. The results taken from the three methods are compared by using both the frequency response and the transient response parameters.
