Title: A question about Razavi's book Post by qiushidaren on Aug 21st, 2006, 1:53am I am analyzing the circuit in problem 2.6(c) of Razavi's book "Design of Analog CMOS Integrated Circuits", but I am confused about the conclusion in the solution manual, it says that the device turns off when Vx=2-Vth+R1I1. But I think that once Vx is larger than 2-Vth, the device will always in saturation region, can someone explain this to me, whether the solution manual is wrong or I am wrong? Thank you in advance!
