In this video I show how to calibrate an MFOS oscillator in which I have used a hand matched pair of 2N3904 NPN transistors. I tried to get this down to one ten minute video but I just couldn't. It is now a two part series. This is part I. I am able to achieve 8 octaves of range. If you have not read the article on Practical Transistor Matching on MFOS at [ Ссылка ] you might enjoy it.
