    Part 4 of microphone technology with Doug Ford, former head designer at Rode Microphones.
    In this video Doug discusses how to design a condenser microphone, in particular the Rode Classic II microphone.
    Many things discussed include:
    External polarisation voltage generation and the relationship with sound pressure.
    The trade-offs involved in bias voltage vs physical construction and sensitivity.
    Diaphragm deformation and its effects.
    CMOS oscillator design for high voltage generation.
    Zener diode noise in relation to the knee type, and how to reduce it.
    Heating and dehumidification advantages of valve based microphones.
    Valve based amplifier design, and blending solid state for improved performance.
