Some Power Amplifier Wizardry in my spare time
Hello, Wizarders! sorry that I haven't posted anything in a while. Lots of other stuff going on. If any of you are getting withdrawal symptoms for circuits and equations, though, why not check out EDN (http://www.edn.com/design/consumer/4398669/The-Class-i-low-distortion-audio-output-stage--Part-2- is part 2, which links back to part 1) for the first two parts of my four-parter on an audio power output stage I started designing a long time ago - before Cypress was founded, so that's when real dinosaurs still walked the Earth! The last two parts will be along during the next month or so.
When I finally get round to building one of these again, I'm sure that PSoC will be a fantastic supervisory controller, with its flexible analog and programmable digital hardware. This will allow the monitoring and calculation of temperatures, power dissipation levels, overload and operating points, built-in timers, power quality analysis, earth loop impedance measurement... so many useful things a great audio power amp might need. If any of you out there are doing or have done any power amplifier supervisory stuff, check out PSoC3, and ping me if you have any questions.
After I've got over the shock of the beginning of the new quarter, my next published Filter Wizard article will likely be on circuits that generate voltage gain using only pure lumped resistors and capacitors. Useful? Don't know, but certainly unexpected! best / Kendall
