Simulation of Amplitude Modulated Resonant Tunneling Diode Oscillator

Paper in proceeding, 2026

Resonant tunneling diode (RTD)-based oscillators have shown promising results in terms of dc-to-rf efficiency and are currently regarded as a viable candidate in enabling terahertz wireless communication. Using a simplified oscillator circuit topology together with a cubic RTD-model we derived the Van der Pol oscillator equation, whose transient response was simulated. The RTD-based oscillator shows clear eye patterns at 50 Gbit/s. However, there appears to be an inherent limitation in the system rise time, restricting the use of amplitude modulation at higher bit rates.
