1. LF: MOSFET gate resistors question (score: 1): Author: Chris Wilson <[email protected]>; Date: Sun, 2 Jun 2019 14:39:29 +0100; Hi all, My pal G6ECH and myself are battling poor drain waveforms in Class D 470 kHz push pull amps. We have two main initial questions. Some circuits show a gate pull down resistor used, some do not; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-06/msg00001.html (8,974 bytes)
2. Re: LF: MOSFET gate resistors question (score: 1): Author: Andy Talbot <[email protected]>; Date: Sun, 2 Jun 2019 15:50:44 +0100; Teh 4k7 on the gate is not a pull down. I assume it is associated with gate drive via a capacitor and diode to give DC restoration. A safe way of driving FETs to prevent them beoing switched perma; /rsgb_lf_group-archives/html/rsgb_lf_group/2019-06/msg00003.html (13,366 bytes)
