Abstract
The present disclosure provides a voltage controlled oscillation device and a wireless transceiver. The voltage controlled oscillation device includes a resonator, an oscillation core circuit, a switch circuit and a control device. The oscillation core circuit is configured to provide signals of different phases to the resonator. The resonator is configured to generate a plurality of different resonance frequencies. The control device is configured to control the connection/disconnection among ends of the resonator through controlling the switch circuit to be on/off, so that the resonator retains two resonance frequencies from the plurality of different resonance frequencies. The control device is further configured to change the retained two resonance frequencies by controlling the switch circuit to be turn on/off. The resonator is further configured to process two resonance frequencies under action of oscillation core circuit, and output a fundamental signal of one resonance frequency.
