Part 4 of microphone technology with Doug Ford, former head designer at Rode Microphones.<br />In this video Doug discusses how to design a condenser microphone, in particular the Rode Classic II microphone.<br />Many things discussed include:<br />External polarisation voltage generation and the relationship with sound pressure.<br />The trade-offs involved in bias voltage vs physical construction and sensitivity.<br />Diaphragm deformation and its effects.<br />CMOS oscillator design for high voltage generation.<br />Zener diode noise in relation to the knee type, and how to reduce it.<br />Heating and dehumidification advantages of valve based microphones.<br />Valve based amplifier design, and blending solid state for improved performance.<br />http://www.rodemic.com/microphones/classic2ltd<br /><br />All videos in this series are here: https://www.youtube.com/playlist?list=PLvOlSehNtuHv98KUcud260yJBRQngBKiw<br /><br />Forum: http://www.eevblog.com/forum/blog/eevblog-609-condenser-microphone-design-tutorial/<br /><br /><br />EEVblog Main Web Site:<br />http://www.eevblog.com<br />EEVblog Amazon Store:<br />http://astore.amazon.com/eevblogstore-20<br />Donations:<br />http://www.eevblog.com/donations/<br />Projects:<br />http://www.eevblog.com/projects/<br />Electronics Info Wiki:<br />http://www.eevblog.com/wiki/
