1. The NMOS transistor in the CS amplifier shown in Fig. 1 has = 0.7 V, = 50 V, = 120 kΩ, = 300 kΩ, = 200 kΩ, = 5 kΩ, = 2 kΩ, = 5 kΩ, and = 5 V.
申論題內容
(a) Neglecting
the channel length modulation effect, the MOSFET is operating in saturation with ID = 0.5 mA and
= 0.3 V. What must the MOSFET's (W/L) be? What is the dc voltage at the drain?
