Design and implementation of a single op-amp PID for RC circuits
A conventional PID will consist of four components namely proportional, integral, derivative and summer. Our study focuses on designing a PID that will use one operational amplifier and some components like capacitors and resistors that could operate a 3.3V supply at 0.25 um technology. The operatio...

| Summary: | A conventional PID will consist of four components namely proportional, integral, derivative and summer. Our study focuses on designing a PID that will use one operational amplifier and some components like capacitors and resistors that could operate a 3.3V supply at 0.25 um technology. The operational amplifier configuration to be used is the two stage CMOS op-amp using Pchannel input pair that has a maximum gain of 91.48 dB.
In order to test our design, our test circuit will compose the following a RC circuit, a voltage divider and a NMOS transistor. Our goal is to regulate a certain voltage in our output that depends on the reference voltage we set ranging from 100mV to 1.5V. The single op-amp PID was implemented and designed using T-Spice tool. |
