ENSC 895: SPECIAL TOPICS: THEORY, ANALYSIS, AND SIMULATION OF NONLINEAR CIRCUITS

Assignment #7:

  • If you have not already done so, please send me a short paragraph describing your project.

  • 1. Let the pair of matrices (A,B) be a passive pair. Is it true or false that the (A,B) is a Wo pair? Why?

  • 2. According to Theorem 3 in
    R. O. Nielsen and A. N. Willson, Jr., ``Existence of hybrid matrices for active n-ports encountered in the analysis of transistor networks,'' Int. J. Circuit Theory and Appl., vol. 7, pp. 65-76, Jan. 1979,
    there are only certain number of principal minors that can possibly be negative in any two-transistor circuit matrix T^{-1}G. Which ones are they?

  • 3. For the flip-flop circuit from Assignment #1, Figure 8 (page 4) in
    A. N. Willson, Jr., ``Introduction,'' Nonlinear Networks. New York: IEEE Press, 1975, pp. 1-5,
    determine the relationship that must hold (among resistances and transistor parameters) in order that the dc equations may possess more than one solution.

  • 4. For the flip-flop circuit from Assignment #4, determine the relationship that must hold (among resistances and transistor parameters) in order that the dc equations may possess more than one solution.
