noise problem in voltage booster circuit

Apr 08, 2007 26 Replies

Hi all,

I developed a simulation of the proposed voltage booster using "Electronics Workbench 5.12"

but it seems that software cannot analysis it. I will be appreciated with your comments and suggestions in this regards.

I do not have EWB in my computer. Please email me a screen capture

(print screen key to put image in copy buffer, then paste into image program, like paint or Irfanview, save as gif)

of the schematic, so I can help debug.

If you email me so I have your address, I'll send a schematic that works in LTspice. Have you got that loaded in your computer? It is far superior to EWB.

Thanks all, esp John Popelish for favours

I will be appreciated with your comments and suggestions for add an AC level (~1V 3KHz) on the DC level (30 to 100 V) of the proposed circuit

This will require optimizing the frequency response of the whole loop. The best response would probably require cascoding the output transistor to minimize the effect of feedback capacitance collector to base on the inverting transistor. I'll go back to the simulator and play a bit.
