In school they teach us how to calculate on NMOS circuits, but we never learned the basics for how to design your own circuit.
I know how to give a bias voltage on the gate. This leads to a current on the drain, which leads to a voltage across the drain and source resistor.
But I never got guidelines on how to design a circuit.
I want BIG signal amplification and drain minimum power doing so.
What resistor should I change to increase amplification?
I'm guessing the drain resistor but I'm getting nonsense readings from LT-spice when I do that.
Please help me I'm getting nervous breakdown over this.
