Response to the following problem:
A current-mirror-loaded MOS differential amplifier is found to have a differential voltage gain Ad of 30 V/V. Its bias current source has an output resistance RSS = 45 kΩ. The current mirror utilized has a current gain Am of 0.98 A/A and an output resistance Rom of 45 kΩ.
If the common-mode output resistances of the amplifier, Ro1 and Ro2, are very large, find Acm and CMRR.
