A frequency divider using interacting self‐sustained pulses in a tunnel‐diode‐oscillator lattice

Abstract

Summary An effective method for frequency division, which uses interacting self‐sustained solitary waves propagating in a one‐dimensional tunnel‐diode oscillator lattice, is discussed. When two pulses are input successively, it is found that there is a threshold separation below which the following pulse is significantly attenuated to disappear on the way, which only slightly influences the leading pulse. This phenomenon results in an efficient frequency divider with a high division ratio, which requires a relatively small number of lattice cells. In this study, we illustrate the fundamental dynamics of the self‐sustained pulse interactions and principal operation of frequency division with several experimental validations.
