Hi everyone, i have an issue about applying a transfer function to an opamp. I know how to get transfer function for a given opamp circuit. Suppose we have a transfer function but we may add additional pole, zero etc to get stable system. I have been working on feedback system, PI, PD and PID controllers. For example, PID controller can have pole, zero and inverted zero or more. I have seen lots of PID opamp circuits but each are in different configurations. Even when i need to insert pole, zero etc to already found transfer function, i struggle how to apply the new transfer function to as opamp circuit. Adding pole,zero etc to transfer function, makes it harder to apply it to as opamp circuit. I mean how can i apply any transfer function i have found to an opamp circuit ?
