Title:
CONTINUOUS TIME Δ-Σ ANALOGUE-TO-DIGITAL CONVERTER AND COEFFICIENT CALIBRATION METHOD THEREFOR, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/166538
Kind Code:
A1
Abstract:
Disclosed are a continuous time analogue-to-digital converter and a coefficient calibration method therefor, and a storage medium. A continuous time Δ-Σ analogue-to-digital converter at least comprises: a voltage comparator and a digital controller. The method comprises: in a pre-set calibration mode, a voltage comparator comparing a pre-acquired first calibration signal with a pre-set reference signal; and according to a comparison result of the first calibration signal and the reference signal, and a pre-set calibration parameter, a digital controller calibrating all pre-set coefficients, which are to be calibrated, in a continuous time Δ-Σ analogue-to-digital converter, wherein the comparison result comprises a high-level signal or a low-level signal.
