ECE 3150 Spring 2009 Week 14 Recitation There is Homework 10 due on Friday. Additional practice problems: (a) What is the logic function of Out ? (b) Design the full complementary CMOS logic with PUN and PDN that implements the same function. Indicate sizing of each transistor so that the logic network will match the large signal resistance of the inverter of size (1p, 1n) in Prob. 3. A B C D Out Out=AC +BD 1

(c) Design PTL with inverters for the same function. What are the input logic values that will generate an uncertain (high-impedance) output signal? A weak logic signal? What are the main problems for the circuit you have design? Suggest a way to remove the possible weak “1” at the output. High-impedance values: A = 0 or B = 0 . Weak logic values: ( A = 1 and C = 0 ); ( B = 1 and D = 0 ) We can add a level restorer and a staticizer to remove the possible weak 1’s. (d) Design a DCVSL circuit, assuming all complements of A, B, C , and D are available. Will there be a weak value at the output?

    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.
