Dear Sir,
I need your support for this op amp circuit. Please refer image attached. I have used dual supply +-5V, IC used LM324SN.
I am suffering with output not getting as per simulation.
The circuit has three sections. First is a Wein bridge oscillator, second section is buffer amplifier (1K resistor used in feedback to limit current) and third is inverting amplifier.
When I connect resistor 465E in inverting amp circuit, output after buffer amplifier gets zero and when I remove this resistor I get 300mv.
I am not able to identify the reason. need your support.
