An active-loaded NMOS differential amplifier operates with a bias current I of 100 microamperes. The NMOS transistors are operated at Vov=0.2 V and the PMOS devices at |Vov|=0.3V. The Early voltages are 20 V for the NMOS and 12 V for the PMOS transistors. Find Gm, Ro, and Ad. For what value of load resistance is the gain reduced by a factor of 2?
