Can u plaease help me to know how can i calculate the power gain of a mosfet amplifier without having the current gain ??
The power gain formula is Ap = Av * Ai but the current gain of the mosfet is almost infinte and there is no formula to calculate it so how can i find Ap ? Should i just calculate the power dilivered to the load by ohm's low that P= Id ( Rd // Rl ) ? But if the question was find Ap would it be right to find the power on the load ?? I don't think it's right but how can i know Ap ?
