Title:
RESIDUE TRANSFER LOOP, SUCCESSIVE APPROXIMATION ANALOG-TO-DIGITAL CONVERTER, AND GAIN CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/098467
Kind Code:
A1
Abstract:
The present application discloses a residue transfer loop, a successive approximation analog-to-digital converter, and a gain calibration method. The residue transfer loop comprises a sampling switch module, a logic control circuit, a residue holding capacitor module, a DAC capacitor array, a residue transfer module, a current-steering element, a reset switch module, and a charge sharing switch module. The logic control circuit sequentially outputs control signals at a preset time interval within a preset period so as to control the reset switch module, the residue transfer module, the sampling switch module and the charge sharing switch module to operate sequentially, thereby achieving a residue transfer.
