Hi all, I notcied that Class-D is working in a switching mode. Like for class A we have 360 conduction angle so the bias point is around the middle.
But I saw a tutorial claims that Class-D has an 0 conduction angle. What does that mean?And how do we choose the bias point for Class-D? Thanks!!
I saw notions that:
ft :
transition frequency,cut-off frequency,unity gain frequency.
Are they the same frequency?
In my understanding, cut-off frequency should be 0.707 of maximum and UGF is when current gain=1.
And how are the considerations of this frequency(if they are the same) in linear...
What method or algorithm dose it use?
As I am simulating a transistor, the S-parameters plot looks so different from the datasheet.
The datasheet should be right since it is given out by measurement.
