    hi
    I am trying to design a Micro-capacitance measuring circuit. somewhere in my processing of the signal I need a demodulator. can any one help me a circuit diagram and short explanation of the diagram for demodulator.

    AM or FM demodulation?

    Could you describe the requirements a bit more clearly?

    Does it have to be built from discrete components, or can you use ICs?

    When is this due?

    Thanks for your contributions.
    The demodulator I want is Phase Sensitive Demodulator (PSD).
    Anyone can help me a circuit diagram of PSD.
    The IC I may have quick access are opamps.

    What are your requirements for the PSD? Frequency, max deviation from center, max signal frequency, etc.?

    When is this due?
