Sorry I always get confused when the term "bias" is used, I don't know what u mean, but if u want to know what I'm trying to do go here :

Read : "Driver design" for info on class E amplifier
Read the title: "Power Link and Internal Power Unit" to see what I'm trying to do.
Look at figure 3
Also u can go here: **broken link removed**
And click on figure 8, that is exactly what I’m trying to do, however I don't know how to implement that feedback in practice, where it says "Feedback current sense" and the inverter connected to the mosfet. So I thought about using a signal from the signal generator, but when I do that I don't know if that class E will still be a class E amplifier (i.e have the properties of a class E amplifier) if I use the signal from the signal generator.
