Adapted from something I saw on the web... I had to scratch my head until I understood C1: it bootstraps Q1's collector load (R2) impedance, turning it effectively into a current source. Gain is accordingly greatly increased. G = ~220 @ 40KHz. +3.3V --- | .-------+-------. | | 5K R1 C1 ...

What are some optocouplers you like that would be good for designs where they're used in unusual ways, like that "HV Opamp" thing JL likes where they're used as the "output stage" of an amplifier? Are any characteristics that I should look for in the datasheet that makes a particular coupler a better performer in an application where linearity is more important than high-speed switching...

So, I had a chance to get back to that calibration gizmo for my biochip front end amplifier (1 nA at the shot noise limit in a 100-MHz BW). It turns out that it's possible to do a very nice job, assuming that the integration cap (C1 in the schematic) has zero inductance, but as much as 0.05 nH blows it out of the water. (Should have thought of that, of course, but oh well.) Try running ...

Greetings, gentlemen, This is the schematic of the CRO x-amplifier I've been investigating lately. It's supposed to provide sufficient potential difference to the x plates in the tube so as to sweep the electron beam left to right in accordance with the timebase setting: https://yandex.com/collections/card/5da36a58f05bf23ffde0742e/ At first I thought this was operating as some kind ...

Hi all, What is the best configuration for those first crucial one or two stages of an audio amplifier? I mean when you're dealing with the very low signal levels you typically get with phono cartridges (anyone remember them? - they're making a comeback!) in particular wrt to minimising noise and distortion? What's best for the front end? Are we talking long-tailed pair or something m...
