For two series connected Nmos, i have apply a Vdd at M2. Please refer to attachment(voltage.jpg).
I am intrested to know the current flow. How to make such calculation?
Other know value is gate voltage of M2 and gate voltage of M3.
Since the Vds2 is Vd2-Vs2 and Vds3=Vd3-vs3, now i dont know what is Vd3 and Vs2, how to calculat this ? cause i need to know the operating mode of M2 and M3...
Attaching three pages from razavi book which deals with your circuit. If you want you can download the book from the eda books upload / download forum.
