Given the availability of NMOS and PMOS transistors that are matched and have kn = kp = 5 mA/V2 and VAn = −VAp = 5 V, design a circuit for an NMOS common-source amplifier with a PMOS currentsource load. Operate each transistor at a dc bias current of 100 μA. What is the output resistance? 100 kΩ 25 kΩ ∞ 50 kΩ
