1 ECE 3150 Homework 1 Due 1/30/2009 before class in the drop box 1. (Simple definition of signals) Briefly (in 1 to 3 sentences) explain the following: (a) Describe the Moore’s law in terms of transistor counts, smallest feature and cost per bit. (4 pts) (b) What is the basic difference in transient values between digital and analog representation when v(t) or i(t) is used in microelectronics? (4 pts) (c) What is the difference in the ambient noise effect between digital and analog signals? (4 pts) (d) A transistor on a 65nm CMOS technology usually drives a capacitance of 100fF. Assume we have a hundred million transistors with V DD = 1V and the system clock is 1GHz. What is the dynamic power consumption? What is the factor that we did not consider here? (4 pts) (e) For the realistic voltage transfer curve of Fig. 1.13, describe how voltage gain affects the input signal range without output saturation. (4 pts) 2. (Large signals and small signals) For the output and transfer characteristics below, (a)

    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.
