| Popis: |
The paper presents results obtained after review and analysis of three mathematical models (Van der Pol, Lienard and FitzHugh-Nagumo) for investigation of dynamics of microwave radio-frequency devices based on a resonant tunneling diodes. A simple circuit of a non-autonomous radio-frequency device based on a resonant tunneling diode was proposed. A simplified mathematical model of Van der Pol was used. Mathematical modeling of electrical oscillation dynamics for the non-autonomous radio-frequency device based on a resonant tunneling diode was performed. Phase portraits of the non-autonomous radio-frequency device, time diagrams and amplitude spectra of its input and output signals in modes of fractional multiplication and division of frequency were obtained. |
