A digital filter model for time-domain analysis of the two-band model [resonant interband tunneling diodes]

Resonant interband tunneling (RIT) diodes show a very high peak to valley ratio, and have been expected to be high speed devices.

Summary:Resonant interband tunneling (RIT) diodes show a very high peak to valley ratio, and have been expected to be high speed devices. This paper presents an equivalent circuit for the two-band model, which describes the behavior of electron waves in RIT structures and derives digital filters which simulate the time evolution of electron waves in RIT structures. The digital filters derived have advantages in terms of numerical stability and parallel realization. In addition, a multi-grid algorithm and an absorbing boundary are presented in order to achieve efficiency for the digital filter. Finally, an example of simulation is shown.
