I really like how you use the ATD as an example. I've been playing with some JFETs and GaAs FETs lately, and it's really helped for understanding how to design these basic circuits using these types of transistors.
sir, in differential pair of mosfet, if the current source can be seen as a M3( mosfet ) that mean the current source ISS is equivalent to M3 ( mosfet). How to calculate the Vgs of M3 if the current source ISS =0.5mA and (W/L)3 is chosen arbitrarily by the designer . Can you give me some ideas sir?, thanks you !
These classes are much better than ones I had at my university time.

What does ATD mean?
@@strongman325 ATD =Arbitrary Three Terminal Device
If I remember correctly or Arbitrary Transistor Device
These lectures... are so friggin good!

You can calculate the Vgs of M3 by Vgs = sqrt(0.5mA/k'). where k'=1/2*(un*Cox*(W/L)3).
Hi Sir, Good Morning ,Please explain me how does Re increases dynamic range in BJT differential amplifier
You can watch his video about Emitter/Source Degeneration. By placing Re, the slope gets smaller, the range increases at the cost of smaller gain.
