Abstract: The present application discloses an oscillation device and a method for oscillation thereof, in which a control signal is generated from a control circuit to a ring oscillation circuit. The ring oscillation circuit generates an oscillation signal with a first signal frequency at start up oscillation, firstly. Further, the ring oscillation circuit modulates an oscillation frequency to drive the oscillation signal change from the first signal frequency to a higher second signal frequency. Thus, the present application provides the ring oscillation device generating the oscillation signal with a lower frequency at starting up oscillation, and then make the oscillation signal change to a higher frequency. Hereby, the present application provides the oscillation signal operated at a higher operating frequency.

Abstract: The present invention relates a multi-shot time-to-digital converter and a time-measurement device. The multi-shot time-to-digital converter includes a time-to-digital conversion circuit and a timing control circuit. The timing control circuit is coupled to the time-to-digital conversion circuit and sending a start signal to the time-to-digital conversion circuit multiple times for measuring a time interval corresponding to the start signal. The time-to-digital conversion circuit obtains a fine phase time based on a plurality of clock signals to measure the time interval and provides a plurality of time-to-digital codes for digital processing. The clock signals have different phases. The time-to-digital codes are further processed to obtain the time-to-digital codes with better resolution.
