Large-Signal Circuit Theory for Negative-Resistance Diodes, in Particular Tunnel Diodes

The large-signal, high-frequency circuit applications of a tunnel diode as an oscillator and as a monostable and bistable switch have been analyzed quantitatively, without any of the customary simplifications, by solving on a computer the system of nonlinear differential equations which describe the diode and the external circuitry. Frequency, amplitude, distortion and switching times are calculated with high accuracy as functions of operating point and circuit inductance. The results are in very good agreement with actual measurements.
