Prof. Kaustav Banerjee 1 UNIVERSITY OF CALIFORNIA, SANTA BARBARA Department of Electrical and Computer Engineering ECE124A VLSI Principles Homework #5 Reading Assignment: Chapter 4, Sections 4.5- 4.9, and Chapter 6, Sections 6.1-6.2 CMOS VLSI Design: A Circuits and Systems Perspective (3rd Edition), Neil H. E. Weste and David Harris, Addison Wesley, 2005. 1. a) The voltage transfer curve (indicate with a sketch of the VTC) It shifts to the right due to weaker NMOS devices. Electron mobility reduces for higher temperature b) Inverter switching threshold It increases c) Gain It also reduces, since the slope of the VTC curve in transition region reduces. When both device operates in low temperature due to sizing ratio VTC is in optimum status (close to ideal case) when NMOS operates in higher temperature, VTC deviates from optimum case. d) Noise margin (low and high) Noise margin Low reduces while noise margin high increases e) Delay Delay increases since the high-to-low transition is slower (higher rise time) f)

    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.
