I also like the simple current sink circuit approach, but it usually takes just a few more parts to get a stable circuit... the most basic design with just a resistor, transistor and op amp tends to "sing"!
See Linear Tech Application Note 105, figure 200 on page 108: https://www.analog.com/media/en/technical-documentation/application-notes/an105fa.pdf You might change the 1 Ohm resistor to 10 Ohm for a 1 V / 100 mA control voltage. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
