Abstract
A delay calibration circuit and method, an analog-to-digital converter, a radar sensor, and a device are provided. The delay calibration circuit monitors a timing relationship between signals in a chip in real time to extract PVT information, dynamically adjusts conversion timing of an asynchronous SAR ADC, maximally utilizes an available conversion time in each cycle of the asynchronous SAR ADC, improves the robustness of the asynchronous SAR ADC, and does not affect the normal operation of the asynchronous SAR ADC.
