Cutoff: v gs v to (channel off, i D = 0) 2. Triode: v ds < v gs- v to (Voltage Controlled Resistor) 3. Saturation: v ds v gs- v to (amp mode) V T , v to : threshold voltage for channel i D 0 for GS v to Cutoff Region ( v gs v to ) v gs v to few charge carriers no channel Cutoff: Use : v gs controlled switch OFF = cutoff v gs v to ON = saturation v gs >> v to V GS i D K 2 v GS v to v DS v DS 2 K W L KP 2 Triode Region: W: width, L: length (channel) v DS v GS v to v GS > v DS + v to , channel wider, resistance lower Slope i D vs....
