WebDie Gegentakt-Endstufe, eine Totem-Pole-Schaltung bewirkt, dass die kurzen Schaltzeiten auch am Ausgang wirksam sind. Die niederohmige Endstufe verträgt höhere Ausgangsströme und verbessert damit die Flankensteilheit des Ausgangssignals. Die eingetragenen Widerstandswerte entsprechen der Standard-TTL-Serie. WebMar 6, 2016 · Re: BJT totem pole questions. Yes, in front of the push-pull pair you already have, but that will lift the 'off' level by Vce_sat which will end up giving you about 1V on the gate in the OFF state. Depending on the MOSFET minimum gate threshold, this may be an issue and cause excessive leakage current when off.

"WebTotem-pole topology can achieve a power factor of 0.99. High efficiency, high power factor, and low cost. T1 and T2 could either be replaced by a PN diode or SiC (depending on voltage output) to be more cost effective. Alternatively they can be replaced by GaN FETs for more efficiency, with less switching losses and lower thermal dissipation. " - Totem pole schaltung cmos
