The NMOS transistor below has Vt=0.4V, and VA=10V which means channel e ff ect is considered. The dc voltage at the source is measured as -0.6V. Assume all three capacitors to be ideal (infinite large). (a) What is the dc voltage at the drain terminal? (b) What is the overdrive voltage at which the transistor is operating? (c) What is the region in which the MOSFET is operating? (d) Find the values of gm and ro. (e) If Y is connected to the ground and a small signal vx is at X, find input resistance Rin and overall voltage gain LaTeX: \frac{v_z}{v_x} Assam Transit on af . Vs = - O . GV i VB = ?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
