Experimental characterization of mutually synchronized voltage edges in point-coupled tunnel diode transmission lines

Abstract

We investigate experimentally the mutual synchronization of oscillating pulse edges developed in dissipatively point-coupled transmission lines periodically loaded with tunnel diodes (TDs). Based on the phase-reduction scheme, the mutually synchronized edges are shown to pass simultaneously the connected points. It then becomes possible to design the phase difference between synchronized edges by the arrangement of connected points. Using test TD lines fabricated on breadboards, the fundamental properties of mutually synchronized edges are successfully validated.
