Latest Patents

Chen is listed as an inventor on 1 patent: “Detection Circuit and Power Management System Including the Same.” The application describes a threshold-voltage generation circuit, a voltage-to-current conversion circuit, and a current-type successive-approximation quantizer. The conversion circuit turns an offset voltage from the signal being detected into a proportional current relative to a generated threshold voltage. The quantizer uses that current to determine whether the signal is above or below the threshold, or to produce a quantized result within a window. The disclosed approach aims to simplify the circuit and lower its cost.
