Sorry, I mean Vdd = Id.Rd+VdDid you draw the schematic?
Vd = (Vcc - Vd)/Rd is an equation that makes no sense whatsoever
I mean Vdd = Vd + Id.Rd so Vd = Vdd - Id.RdIn a class A amplifier, what do you expect Vd to be? That is what equation answers.
True. But what if you want to set DC voltage at the drain equal to Vdd/2 =15V/2 = 7.5V? To get maximum allowed voltage swing at the output?I mean Vdd = Vd + Id.Rd so Vd = Vdd - Id.Rd
that's great, thanks in advanceTrue. But what if you want to set DC voltage at the drain equal to Vdd/2 =15V/2 = 7.5V? To get maximum allowed voltage swing at the output?
So now the voltage at the drain can swing from +7.5V up to 15V and down by a 7.5V also, from +7.5V to 0V
Look here to see why
