Controlling high-frequency chaos in resonant tunneling chaos generator circuits

Controlling chaos signal patterns at 12 GHz was demonstrated on the resonant tunneling chaos generator circuit. This was made possible by implementing the reset switch, which resets the circuit to various initial conditions periodically. The reset period was set so short that the initial condition errors can not grow significantly. Thus the circuit repeated identical signal patterns, and they can be clearly observed by a sampling oscilloscope. The application of this circuit to fabricate ultrahigh speed pulse pattern generator was also discussed in this paper.
