Low current HF current source
« on: November 23, 2020, 06:07:09 pm »
I am a lab-less armchair engineer these days of covid. I had a bit of a brainwave regarding my arch enemy the Convenor. So here's one to pump up Mr Howlands tires. R1=R3, R2=R9+R1, same ratios on both Amp channels. Watch out for generator Zo. Assumed to be 0. Mad resistor tolerances or trimming nightmare only you can decide! But worth a go and dirt cheap. Just how stiff it is I'm not sure? Old age?
