Experimental observation of synchronised oscillating edges in electrical lattice with series‐connected tunnel diodes

Herein, the authors experimentally characterise the dynamics of voltage edges oscillating in a transmission line with regularly spaced two series‐connected tunnel diodes (TDs). They clearly observe the mutually synchronised behaviour of the edges supported by each TD, which can be utilised to generate large‐amplitude and low‐phase‐noise oscillatory voltages. They establish the fact that the response time of the device for state‐transition is the key to qualitatively determine the edge oscillation, i.e. a single large‐amplitude edge develops for sufficiently a large response time, whereas two larger and smaller edges coexist and are synchronised for short response time.
