College of Engineering Department of Electrical Engineering and Computer Sciences Elad Alon Homework #2 EECS141 Due Thursday, September 10, 5pm, box in 240 Cory PROBLEM 1: VTC In this problem we will analyze the noise margins for a chain of gates, Fig. 1a. The VTC has four segments, where the two curved regions can be approximated as quarter ellipses. a) Add the DC voltage sources to Figure 1.a. that you would use for modeling noise coupling to the input and output of gate M 2 . You should arrange these voltage sources so that they would both impact the noise margin in the same way (i.e., if the voltage source at the input decreases the noise margin, the voltage source at the output should also decrease the noise margin). b) Determine the noise margins (as defined in lecture) for gate M 2 when noise couples only to its input. We want a numerical answer in Volts, not one based on just looking at the VTC. c) Are the gates M4 and M5, whose VTCs are shown at the top of the next page in Figures 1.c and 1.d, digital? Is the cascade of the two gates (Figure 1.e) digital?
