Hi guys,
I know it's a very elemental question, but I was having a look at several book and I couldn't find a clear explanation
Why is it normal to place an inductor between NMOS drain and power supply in a power amplifier? I know it's a choke inductor... but I cannot see the point. Why is it "needed"?
And why don't we do the same in small signal amplifiers instead of using a resistor?
Thanks in advance
