WebDifferential amplifier is designed with active loads to increase the differential mode voltage gain. The open circuit voltage gain of an op-amp is needed to be as large as possible. This is got by cascading the gain stages which increase the phase shift and the amplifier also becomes vulnerable to oscillations. http://www.ittc.ku.edu/~jstiles/412/handouts/2.4%20Differnce%20Amplifiers/Differential%20and%20Common%20Mode%20Gain%20lecture.pdf
