Unformatted text preview: ECE124d/ECE256C Quiz 7 The logic circuit above has a current draw in a typical triangular shape -— every 5nS it draws a peak of lSAwith a rise of IOOpS and a fall time of 400 p8. The power supply has the capability of supplying 6A DC at 1.8V, but will supply no higher currents and will not supply current beyond 1.8V and has no bandwidth restrictions (i.e. this is an idea power supply). 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.
