Current source for BOZ

[Peter Daniel]

fcel, Elma is a switch without resistors. You don't have to calculate the values, just use the ones from Pass D1.

Current source voltage reference

The voltage reference for the curent source is five green LEDs in series. 5x1.8 volts gives 9.9 volts. These are biased by a 100k resistor to ground. Sorry for the confusion as the schematic was a Spice simulation drawing that I didn't redraw for exact parts.

Thanks, I figured it out after posting. But always good to get a second opinion. I will try it out.

I knew there was a nine in there somewhere

AudioFreak, thanks for jumping in. Maybe you can help with correcting people's spelling also.... Remember kids, drinking and typing don't mix!

Stereo Typing

You live in Oz and you don't drink beer? I don't drink either, but I still can't type. I usually can do math though....

H.H.

P.S. I believe that i is supposed to be capitalized.
