firing circuit using mosfet
you should connect Vo op amp to totempole circuit that contain 2 transistor after it you should connect tow emitter by resistor to the gate of mosfet toprotect 2 transistor from second break
in totempole a pnp &a npn are conected together from emitter and base colector of pnp to Vcc ,colector of npn to ground tow base connected to op-amp output
bd135 bd138 are good choice
