Utilize the voltage-controlled oscillator to continuously output signal with acceptable frequency without utilizing phase lock loop

Abstract

The present invention continuously generates a signal at an acceptable frequency without utilizing the PLL to modify the operation of the VCO. When the VCO is initialized properly to output a signal at a specific frequency, the VCO operates on its own to continuously output signals, and the VCO state is modified at regular intervals. Thus, when the interval is short enough and when the VCO is modified to the initial state every time, the VCO state will not deviate significantly from the initial state during these intervals. Thus, the VCO continuously generate signals with frequencies acceptably closed to the specific frequency. That is to say, the invention utilizes the injection lock to modify the operation of the VCO. To compare with the convention skills utilizing the PLL which has to feed back the signal generated by the VCO to the PLL for modifying the VCO state dynamically, the utilization of the injection lock simplifies the hardware and streamlines the process. Thus, the invention is an alternation to the convention technologies with lower cost and similar accuracy.
