Part 5 - Doug Ford explains the design of Electret Microphone circuits, and all the associated traps:<br />Transconductance, correct biasing, and temperature effects, leaky JFETS, non-linear clipping & headroom, current noise and voltage noise, and pseudo bias resistors.<br />Also, the non-intuitive concept of higher resistance = less noise, and how this applies to electret biasing.<br />And what is a soggy circuit board and why is it important?<br />Forum: http://www.eevblog.com/forum/blog/eevblog-611-electret-microphone-design/<br />All the microphone series videos are here: http://www.youtube.com/playlist?list=PLvOlSehNtuHv98KUcud260yJBRQngBKiw<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/
