Latest Patents

Shen is associated with 1 patent: “Differential Successive Approximation Register Analog-to-Digital Converter with Dynamic Input Common-Mode Voltage Control and Associated Method.” The invention describes a differential successive approximation register (SAR) analog-to-digital converter with a comparator, sampling circuit, two capacitive digital-to-analog converters, SAR logic, and a common-mode voltage control circuit. During the sample phase, the sampling circuit provides a differential input to the comparator. During the SAR phase, the logic controls the capacitive converters, while the control circuit dynamically adjusts the comparator’s input common-mode voltage so that it has different levels in the two phases.
