what is this book\'s name?
20 pts) The drain current of long channel MOSFET is given as follows: los=%, enVes-VrmVD,VD, in linear region he 2r et,VGS-VT,2in saturation region Vos-V in saturation region 08 2mL a) Derive the transconductance and output conductance in saturation region b) How would you modify the above equation when a channel length modulation effect is dominant? Find the output conductance of this case. c) Sketch the drain current as a function of gate bias when Vd. is small. d) How would you define a threshold voltage in a problem (c c) What is going on below the threshold voltage you define in a problem (d. Remember that you are supposed to have \"ZERO\" current below threshold voltage f) What will happen if you get m-2 instead of m 1 which is assumed in a square- law model? Explain as much as you can. 8) A cutof frequeney is given as f 2Deriv the exact fomula of cutom frequency using a transconductance you obtain in prob. (a), and explain what you would do to obtain higher cutoff frequency.
