Control and observation of high-frequency chaos in the resonant tunneling chaos generator IC

The direct observation of the chaos signal patterns in a microwave frequency range was demonstrated on the resonant tunneling chaos generator circuit. It is difficult to observe such non-periodic signals because one must use a sampling oscilloscope. To overcome this problem we introduced a control circuit which resets the chaos generator circuit repeatedly to output identical signals. This permitted us to observe seemingly random patterns. We also discussed the extension of this control technique, which leads to various applications.
