The EEVblog lab continues to get upgraded. Some more shelving installed in the office cubicle. Another lot to go in the main area, and a new island bench to come as well. Still have 3.7m of ESD matting left over from that 10m roll. They fitted just perfectly in the …

Part 5 – Doug Ford explains the design of Electret Microphone circuits, and all the associated traps: Transconductance, correct biasing, and temperature effects, leaky JFETS, non-linear clipping & headroom, current noise and voltage noise, and pseudo bias resistors. Also, the non-intuitive concept of higher resistance = less noise, and how …
