Re: Henry's current transformer problem
Andy and analogspiceman Thank you for your replies. Actually, I am not sure what I was thinking for the path length = Ie! It should of course be Pi * D where D = (Internal Diameter + External

Re: Need help to design a transimpedance amplifier
This is the case when first creating a source of noise, and then heroically fighting with them. It is better not to use a charge pump to get negative voltage. You can build tranimpedansny amplifier of

Re: LT1171 model: syncronization not working
To answer the OT question. The VN2222 was a fairly generic ~5 ohm,60V vfet by modern standards. Similar devices are things like the generic? 2N7000 series available from many vendors. So an sot23

Re: Need help to design a transimpedance amplifier
Check the datasheet for the OPA 2846: Vn=1.2nV/sqrtHz, In=2.8pA/sqrtHz that means the OSI (optimum source impedance) is 428 ohms. The 100k resistors in the non-inverting inputs alone introduce 88uV

Re: LT1171 model: syncronization not working
Matt, I just looked at it, and it looks as if SOME of the LT1171's switching pulses are synchronized with the Vc input pin. Those ones have a narrower pulsewidth than the ones around them. Maybe it
