1Stability of the object's composition
If oscillation nodes of multiple LC resonance oscillators are connected directly via resistance element, then synchronization between oscillators is achieved, but load on oscillation nodes increases making high frequency oscillation difficult
Solution Approach 1:
The patent introduces a buffer circuit as an intermediary component between the oscillation nodes of multiple LC resonance oscillators. This buffer circuit acts as a mediator that transfers synchronization information between oscillators without directly connecting the oscillation nodes through resistance elements, thereby avoiding the increased load that would prevent high frequency oscillation while still achieving synchronization.
2Ease of operation
If output from ring oscillation circuits is connected directly via conductive wiring, then signal distribution is achieved, but load on ring oscillation circuit increases making high frequency oscillation difficult
Solution Approach 1:
The patent introduces a buffer circuit as an intermediary component between the ring oscillation circuits and the conductive wiring. This buffer circuit mediates the signal distribution function, allowing outputs to be distributed to multiple destinations without directly connecting the ring oscillation circuit outputs to the wiring, thereby avoiding the increased load that would prevent high frequency oscillation.
3Speed
If multiple oscillators are synchronized without direct connection of oscillation nodes, then high frequency oscillation is enabled, but device complexity increases due to additional conversion elements
Solution Approach 1:
The patent segments the synchronization function into separate buffer circuits for each oscillator, rather than using a complex interconnection network. Each buffer circuit independently manages the signal transfer for its associated oscillator, dividing the overall system into manageable, modular units that achieve high frequency oscillation without requiring a monolithic complex structure.
