EE 307A W07 MIDTERM EXAM #1 Braun CLOSED BOOK + 1 Cheat Sheet State assumptions and show work. Print Your Name: SOLUTIONS No unauthorized help given or received. I will not discuss this exam with another student until after 11:00 today. Signature: Braun Assume that body connections of all NMOS transistors are grounded and PMOS bodies connect to + V DD . Part 1 NMOS logic gate. R L = 50 k Ω , k N = 100 μ A/V 2 A) For the NMOS gate to the right, write a Boolean expression for the logic function obtained at V OUT . G F E D C B A V OUT + + = ) ) ( ( B) Assume that γ = 0.4 V 1/2 . Please list the name(s) of any transistor(s) in the NMOS gate in which the body effect could influence its operation. Transistors A, B, C, D, E, and F can all have their source voltage higher than the voltage of their grounded body connections. C) Assume the gate drives a load capacitance of 20 pF. The propagation delay t PHL would decrease, if the gate had a resistor R
