Abstract
An oscillator and an operation method thereof are provided. The oscillator includes a current source, a memristor, a switching circuit, and a control circuit. The switching circuit is coupled to the current source and the memristor. The switching circuit is configured to transmit a bias current provided by the current source to the memristor, and determine a flow direction of the bias current in the memristor according to at least one control signal. The control circuit is coupled to the switching circuit to provide the at least one control signal. The control circuit is configured to detect a representative voltage of the memristor. The control circuit changes the at least one control signal according to a relationship between the representative voltage, a first threshold voltage, and a second threshold voltage to change the flow direction of the bias current in the memristor.
