hi sir , In the video at minute 17:24, I would like to understand why in the ib2 statement you took the volt values of rb1 and r to be positive and my understanding is that they are negative Therefore, the expression of v1 will be -v1/100 .

@fouazhdib6813 Good question. Given that V1 is applied to the base of NPN transistor T2, as V1 voltage increases, the base current of T2 increases as well. Therefore ib2 = v1/(100+2rb). Here are a few more examples of differential amplifiers: Instrumentation Differential Amplifier kzbin.info/www/bejne/aKmtoaScmt2mhsk Differential Amplifier Gain, CMRR kzbin.info/www/bejne/sGnJaJyQms5ombs Differential Amplifier Design with BJT & JFET transistors kzbin.info/www/bejne/sHzKhIysoJx9d68 I hope these videos are helpful.

The BJT layout is basically a Gilbert Cell
