| 1. An electrical nonlinear pulse oscillator, comprising:
a nonlinear transmission line; and
a nonlinear amplifier having an input to accept a first signal and an output to provide a second signal, the nonlinear amplifier
coupled to the nonlinear transmission line in a closed loop arrangement,
wherein the oscillator is configured to propagate along the nonlinear transmission line at least one nonlinear pulse having
a target amplitude,
and wherein the nonlinear amplifier automatically amplifies or attenuates the first signal based at least in part on an average
voltage of the first signal and/or the second signal.
