Hello rsgb, Some Class D LF / MF amps use a diode to DC restore the waveform after the FET driver chip to the gates. Why do they do this, I am thinking the negative part of the waveform would turn OF
Hi Chris, Maybe it helps to show a concrete schematic together with your question. I find reverse diodes quite useless, at least when MOSFETs are used. It may be a different thing with bipolar transi
I assume we're talking about the series C from driver to gate, then a high value leakage R from gate to ground, and a reverse biassed diode in parallel with this. AC coupling without any DC restorati
