Re: LF: push/pull (score: 1): Author: "Rik Strobbe" <[email protected]>; Date: Tue, 14 Jan 2003 14:30:10 +0100; Hello Uwe, power-FETs do have rather large gate-source capacitances that can differ from FET to FET. For the popular IRF450 Cgs is about 2nF, variations between FET's can easily be a few 100pF. If th; /rsgb_lf_group-archives/html/rsgb_lf_group/2003-01/msg00132.html (11,630 bytes)
