Abstract: | A generation scheme is proposed for multiphase oscillatory signals based on mutual synchronization of the oscillating pulse edges developed in point‐coupled transmission lines periodically loaded with tunnel diodes (TDs). When supplied with an appropriate voltage at the end of a TD line, a pulse edge is shown to exhibit a spatially extended limit‐cycle oscillation on the line. When two TD lines are dissipatively coupled, such edge oscillations are mutually synchronized such that two edges simultaneously pass the connecting cells. Based on this observation, the scheme employs multiple point‐coupled TD lines, wherein the first and last lines are linked at the same position. Its design criterion is obtained by applying the phase reduction method to the transmission equation of a TD line. In addition, several time‐domain calculations demonstrate the validity of the scheme. Copyright © 2016 John Wiley & Sons, Ltd. |
