Title:
ON-CHIP CLOCK CIRCUIT AND ON-CHIP CLOCK SIGNAL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/121358
Kind Code:
A1
Abstract:
An on-chip clock circuit and an on-chip clock circuit-based on-chip clock signal generation method. The on-chip clock circuit comprises: an adjustment circuit (100), comprising a counting circuit (110) and a generation circuit (120), the counting circuit (110) being connected to the generation circuit (120), the counting circuit (110) being used for counting a chip clock cycle within an initial pulse width of a clock signal inputted by an off-chip charging device, the generation circuit (120) being used for generating, on the basis of a counting result of the chip clock cycle, an adjustment signal for adjusting the chip clock cycle; and an output circuit (200), connected to the generation circuit (120) and used for adjusting the chip clock cycle on the basis of the adjustment signal, so as to output the clock signal matching a clock cycle of the off-chip charging device. The clock circuit is capable of synchronizing the chip clock cycle with the clock cycle of the off-chip charging device, lowering accuracy requirements for a clock signal of an external charging device.
