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.

Abstract: A range detection device and a method for range detection thereof are disclosed. An optical sensing element receives a reflected signal of external light signal for triggering a transformation element to generate an electrical signal of receiving detection. Range detection data are generated to an operation processing unit according to the electrical signal of receiving detection and an electrical signal of reference. A plurality of first item data of the range detection data are compressed and operated to generate a plurality of first operation data to be stored as stored data. Further, the first item data correspond to a plurality of first storage addresses. The first operation data correspond to a plurality of second storage addresses. A first address amount of the first storage addresses is greater than a second address amount of the second storage addresses. Thereby, more storage addresses will be spared and hence extending the detection range.
