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.
