Hi,
I don't know what the LTspice trying to show me. In Transient, if I set 2 second stop time, the osc (voltage booster) showing nothing boosted (just showing around 8V which is its supply voltage). If I set 2 mili-second stop time without changing any parts then I can see the boosted output of more than 20 volts. WHAT I should understand ?
(I made the osc in real world. When I measured output with my DMM, it whows 18V just first half a second then starts to show 8V. Maybe it has high impedance output which cannot drive my DMM?)
