Tunnel diode oscillation, flip-flop switching and Goto twin operation have been characterized on the basis of numerical integration of a nonlinear differential equation representing transient behavior in the simplified, lumped equivalent circuit. The results have provided some information for the maximum utility of a tunnel diode having a given figure of merit. A useful relationship is given for single diodes, in which switching time vs external-circuit time constant L/R is shown for various device figures of merit. Another relationship is given for twin diodes in plots of cut-off frequency vs L/R. The study is then extended to the case of oscillator diodes.
