In this video, we discuss the basics of differential amplifiers. Starting with a simple circuit of a differential amplifier with MOSFETs, the ideal and real properties as well as important parameters such as the common-mode and differential-mode gain are explained. 
Finally, some other possibilities to build a differential amplifier are briefly presented.
