Title:
DECODING CIRCUIT AND CHIP
Document Type and Number:
WIPO Patent Application WO/2021/209067
Kind Code:
A1
Abstract:
The present invention provides a decoding circuit and chip; said decoding circuit comprises a charging and discharging unit, a capacitor, and a conversion unit, connected in sequence; said charging and discharging unit is configured to: charge and discharge the capacitor, and the ratio of the total time consumed for charging the capacitor with any amount of power to the total time consumed for releasing the same amount of power on the capacitor is a preset value; the conversion unit is configured to: if the voltage of the capacitor exceeds a preset voltage, output a third level, otherwise, output a fourth level. Such a configuration reduces the calculation burden of an MCU; eliminates the influence of noise on a communication signal, and increases the effective communication distance of the HBS protocol; it adapts to communication signals of different clock cycles. The invention solves the problems in the prior art of a relatively heavy computational burden of an MCU, there being a contradiction between error correction and communication distance, and poor adaptability to communication signals of different clock cycles.
