Abstract

This paper introduces the first robust self-sustained electrical soliton oscillator. It self-starts by amplifying background noise to produce a stable train of periodic electrical soliton pulses. The oscillator is made possible by coupling a nonlinear transmission line with a unique amplifier that tames the instability-prone soliton dynamics. Two experimental prototypes, built at the discrete level, fully demonstrate the detailed operation of the circuit. The soliton oscillator is an electrical analog of optical soliton mode-locked systems
