Re: Vdsat in weak inversion
That's fine. Don't be afraid of the math, very seldom it needs more knowledge than the 4 basic arithmetic operations. On the other hand - for an overview it's not necessary to retrace all the formulas and equations - just believe the author. During a first overview reading it's enough to keep in mind which parameters - i.e which MOSFET properties are related with each other - otherwise you'd probably lose the desire to go on reading - and lay the book away ;-).
Only if you want to really understand the full context of a special property dependency, then dig deeper and try and retrace and understand the equations. If then you have difficulties to understand such a context, you're welcome to return to the forum with your question. Don't forget to clearly describe the problem and what - and perhaps why - you don't understand (this special context).
