how does one build a high current (>5A peak) high speed FET gate driver with BJTs? this is just for autistic dinking around in LTspice, i know the practical solution is to use a $1 gate driver IC. pic related wastes a shit ton of power on R1 yetstill shows pretty awful current amplification. this FET should be able to take like 4A peak (fed by an ideal voltage source at 12V) while i'm seeing only roughly +2.5A and -3.0A peak in simulation. what am i doing wrong?
