You wait for ages, then two come along at once
Two pieces out on the same day for you! Firstly the promised Filter Wizard on getting AC voltage gain out of just resistors and capacitors. Just a nichy little bit of network theory, but still a bit of fun as the winter draws in: http://www.analog-eetimes.com/en/ac-voltage-gain-using-just-resistors-and-capacitors.html?cmp_id=71&news_id=222904234. And then the third part of the Class i amplifier series on EDN, for all you audio fans out there: http://www.edn.com/design/consumer/4401234/The-Class-i-low-distortion-audio-output-stage--Part-3-. Always happy to hear from you with suggestions for topics that I should cover in future articles. Thinking of doing a regular active filter article next, with a little program for calculating component values for the Friend single-amplifier filter in lowpass notch and highpass notch forms, using preferred values but still getting good response accuracy. Interesting? Let me know.
