[Amps] matched MOSFETs (score: 1): Author: Walter Muth <wmuth@rbwelektronik.de>; Date: Thu, 30 Oct 2003 11:25:34 +0100; Hi, what would be the best parameters you can give to characterize a "matched pair " for a high power push-pull amp design ( lets think about 600watts) Vgs(th) and gfs ? What tolerances may be accept; /archives//html/Amps/2003-10/msg00294.html (6,571 bytes)

Re: [Amps] matched MOSFETs (score: 1): Author: Steve Thompson <g8gsq@qsl.net>; Date: Thu, 30 Oct 2003 14:18:47 +0000; Provide separate bias setting pots and there's no need to match Vgs. +/- 10% on gm was a normal selection when I was on that side of things. If the devices come from the same batch code, use separate; /archives//html/Amps/2003-10/msg00300.html (7,274 bytes)
