Synchronization of chaos in simple circuits with dependent switched capacitor

This paper considers chaotic circuits that includes dependent switched capacitor (ab. DSC) and its master slave system. The DSC function is instantaneous short of one capacitor at the moment when its voltage reaches a threshold. The chaos generation can be guaranteed theoretically. If master chaos does not include the homoclinic orbit, the master-slave system exhibits synchronization of chaos, otherwise it exhibits the switching of them. As an example circuit, we select Wien bridge oscillator with DSC and have confirmed the theoretical results in laboratory experiments
