Part Number: OPA392
Tool/software:
I am trying to implement a differential charge amplifier, can some one please let me know what is wrong with my simulation.
Sensor is piezo with 11 nF capacitance, frequency of range is 10 Hz to 15 KHz, minimum signal is 10s of femto charge.
signal generated by piezo is very faint sine wave. Please let me know what is the problem.
