Title:
TIME DOMAIN INTERLEAVING ANALOG-TO-DIGITAL CONVERTER SYNCHRONIZATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/130734
Kind Code:
A1
Abstract:
The present application belongs to the field of control systems. Disclosed are a time domain interleaving analog-to-digital converter synchronization method and apparatus. The apparatus comprises: a time domain interleaving analog-to-digital conversion module, wherein in a first state, an input end thereof is connected to a signal input end, and the time domain interleaving analog-to-digital conversion module performs interleaved sampling on a target analog signal by means of a plurality of analog-to-digital conversion sub-modules, and outputs a multi-channel target digital signal; a calibration module, wherein an input end thereof is connected to the time domain interleaving analog-to-digital conversion module, and in the first state, the calibration module calibrates the multi-channel target digital signal according to a delay error value, so as to obtain a calibrated multi-channel digital signal, and the delay error value is determined in a second state and according to a reference analog signal and a synchronization control signal, the reference analog signal being in clock synchronization with the time domain interleaving analog-to-digital conversion module, and the synchronization control signal being in phase synchronization with the reference analog signal; and a waveform generator module, which is connected to the time domain interleaving analog-to-digital conversion module in the second state, is also connected to the calibration module, and is used for outputting the reference analog signal and the synchronous control signal.
