Above is the load power
Hi People,
I created this npn transistor circuit and it works fine. So basically, it receives this square wave impulse (0 to 2V) and send it to the 10 Ohm(Load) to be amplified to become (0 to 10V).

Question: How to simulate the same way (Load Power Output should be about same) but using pnp transistor because I need the green highlighted part in the diagram to be absolutely grounded ( 0 V at all time) ? Probably can simulate a simple LT spice circuit to demo

Thank you for reading

 

Hi MRsss,
I would recommend every time you post a LTS sim, please post the asc file, so that we can run the sim.

Update:
Post the asc file

 

The 2N2222 in post #1 would burn out. Don't forget to choose a PNP transistor which can comfortably handle the 1A load current.

Ya i know , but although i switched it with pnp, the power i get on the load is low.

 

hi Mrsss,
Check this option.

Hi Eric, it works fabulously. I could not figure out for a long time. Thanks a lot really
