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 !
