It's a cheap and cheerful (relatively compact) boat anchor, I'm curious if it could be good for doing any useful low-frequency control system loop analysis a la: Unfortunately it only seems to include some kind of shaped noise as a source for gain/phase measurement but might still be useful for some stuff.. The beefier 3562 includ


Short Circuit Protected Constant Current Supply

Here are the documents for a short-circuit protected constant current supply for making silver ions and other uses. The current can be adjusted from 100uA to 20mA. The compliance range is 320V. The polarity swap is on a separate pcb not shown here. The zip contains the LTspice ASC and PLT files, and the Diptrace schematic and pcb files. The pcb is hand wired for the moment, so the n...

There used to be a bunch of low-barrier schottky diodes with Cjo < < 1 pF and equivalent series resistance < 5 ohms, SC79 package. BAT63 SMS1546 SMS3927 but they seem to be all gone. Strange. SMS3922 is available, with C=0.7 pF and Rs = 9 typ. Maybe I can use a small phemt as a diode. It seems as if quantity-billion ICs keep killing off fast discrete parts. -- If a man wil

The foamers have come to the conclusion that a reason their tracks get "dirty" and cause power drop-outs is in large part due to nickel oxides deposited on the nickel silver rail surface from micro-arcing and microscopic pitting caused by the pick-up wheels. So they look for a surface coating or cleaner that reduces micro-arcing (if that really is the main reason) but doesn't affect tra...

Gentlemen, When talking about common-emitter configuration BJT stages, is it feasible to get a voltage gain of 400 in one stage or would it be better to cascade two stages of 20? I'd really prefer to use just one stage if it can be done with stability. The input signal will be up to 20mV p-p and supply voltage 12V. cheers, CD.
