Latest Patents
Liu's latest patents include innovative designs for successive approximation analog-to-digital converters (SAR ADCs). One of his patents describes a SAR ADC with an auxiliary prediction circuit. This configuration includes at least one capacitor with first and second terminals, where the first terminal receives an input signal, and the second terminal selectively receives reference voltages. A first comparator is utilized to compare an adjustable reference voltage with the input signal, allowing for efficient switching of the capacitor connections based on voltage comparisons.
Another significant patent focuses on a SAR ADC with a window predictive function. This design features two capacitor digital-to-analog converters (DACs) that receive separate input signals. The system employs coarse comparators to assess the outputs against a window reference voltage, enabling the SAR controller to bypass certain phases of conversion when the outputs fall within a predictive window. This innovation enhances the speed and efficiency of the conversion process.
