EECS 170D Homework #2 Due in class Tuesday October 23 rd , 2007 Problem 1: Diode Connected Load VIN VDD M1 M2 VOUT 100k VDD = 2.5V V t = 0.5V L M1, M2 = 0.25 μ m W M1 = 1.0 μ m W M2 = 2.0 μ m L S = 0.25 μ m k n = 100uA/V 2 λ = 0 V -1 γ = 0.2 V 1/2 φ F = -0.3V Consider the inverter circuit shown in Figure above with an ideal square-wave input. Assume that short-channel effects are negligible – meaning V DSAT >> V DS , V GS -V T. a- Find V OH , as a simplification, ignore the body effect , i.e. γ = 0 V 1/2 b- Now qualitatively (i.e. without equations), explain how V OH will deviate from what you calculated in part (a) if the body effect is taken into consideration. c- Repeat parts (a) and (b) for V OL Hint: Both the load and driver transistors are NMOS , so the answer cannot be 2.5V and 0V!
