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).

Thank you.
@@STEMprof Cool! Very interresting, i will look your video. Thanks a lot.
@@bobdoritique7347 My pleasure, Hope the additional circuit videos are interesting as well.
The BJT layout is basically a Gilbert Cell
Thanks for comment. That's also mentioned in the video see 33:40.
