Dear all,
Have anyone ever used this tutorial widget of class E amplifier design?
(you can get it easy by google the keyword "tonnesoftware")
I don't understand lots of parameters which should be filled in the blank for completing the circuit design.
I hope that anyone could discuss the following listed parameter with me.
Saturation voltage: Does that just mean that the minimum voltage at drain node to ensure the transistor operated at saturation region. If I am right, how to evaluate the threshold voltage precisely of switching transistor?
Network Q : Does that mean the Q factor of sole series RLC. The Q could be expressed as equation 1/R*(L/C)^0.5.
Falltime : I don't have any ideal what's the influence of this parameter in class e amplifier design.
If I am wrong, please correct me.
Beside that, I found that there are two selection modes on the right side( either No L-net or L-net)
What's the main difference by these two options?
The above two images show the difference in the corresponding mode.
Does 50 ohm of Rload in the L-net mode acts as the internal resistance of the measurement equipment?
Does 0.36382 ohm of Rload in the No L-net mode acts as the parasitic resistance of the antenna coil which shown as an inductor with 128.107nH?
Any help is highly appreciated.
best regard,
Joseph
