I have an OPAMP circuit that its output increase steadily without cahnge in the input. I guess the issue is in the transfer function of the circuit and its stability.I want to calculate the transfer function of my circuit but I do not have any idea about that.Could you please help me to calculte the transfer function?
5 volt is generated by a switching regulator called MC34063 and the opamp is a LM358 and I use a UGN3503 Hall Effect sensor
