I decided to use a npn tranny in common base mode (because it has to be non-inverting) to drive a P-type mosfet from a 555. Works well in LTSpice. I tried simulating it both with and without a decoupling cap connected to the base - seemed to make very little difference, so I can live without it. However, is there a good reason I should decouple the base, considering the transistor is just being used as a switch-with-gain?
Thanks folks
