Response to the following question:
A MOS differential amplifier is designed to have a differential gain Ad equal to the voltage gain obtained from a common-source amplifier. Both amplifiers utilize the same values of RD and supply voltages, and all the transistors have the same W/L ratios. What must the bias current I of the differential pair be relative to the bias current ID of the CS amplifier? What is the ratio of the power dissipation of the two circuits?
