For this week’s QSPICE schematic capture, we have a circuit simulation built by our friend Morad Tamer, a senior ECE student. This simulation showcases a discrete MOSFET gate driver design, the key feature being cost optimization at the expense of bootstrapping capabilities. MDriverV2.3.qsch (18.3 KB)

Look at how bad the emitter junction is in the second stage. It is not rational to use the 1n4148 diode to accelerate the shutdown of the pulse transistor. It is better to use a Schottky diode.
