hi,
my senior have given me a circuit to make a pcb and test. I have made that. but I didn't understand the output as I think that some thing wrong in the circuit.
circuit consist of a mcp6022 opamp. apply 20mV ac, no R1, but Rf = 40 M ohm at inverting terminal.
non-inverting terminal is connected to ground.
my question is that without R1 will this circuit work. if yes then what will be the output voltage.
I have uploaded the circuit diagram.
