Amplifier circuit - NMOS mode of operation? Gain?
Ok I have the following circuit, with values of variables:
\$\displaystyle R_{1} = 1 M\Omega, R_{2}=10k\Omega,~~ k_{n}C_{ox}\frac{W}{L}=1mA/V^2\$ , and \$V_{T}=1V\$.
1) When \$v_{IN}=0\$, calculate ...

Transistor in saturation mode?
I was wondering why do we so often want out transistor to work in saturation mode? Ie. For a MOS Current Steering Circuit we want our transistors to operate in the saturation region....

How do I saturate an NPN transistor?
I understand that in "saturation mode", a BJT functions as a simple switch. I've used this before driving LEDs, but I'm not sure I understand clearly how I got the transistor into that state.
Does a ...

How do BJT transistors work in a saturated state?
This is what I know about NPN BJTs (Bipolar Junction Transistors):
The Base-Emitter current is amplified HFE times at Collector-Emitter, so that Ice = Ibe * HFE
