Latest Patents
One of his latest patents is a "Successive Approximation Register Analog-to-Digital Converter." This invention includes a comparator circuit, a capacitor group, an additional capacitor, and a control circuit. The comparator circuit compares voltages at its input terminals to generate a comparison result. The capacitor group and the additional capacitor are coupled to the first input terminal. The control circuit manages the voltages of the capacitors based on the comparison result. In the first period, the control circuit provides a first voltage to the first input terminal and the additional capacitor while supplying an analog signal to the capacitors. In the second period, the control circuit stops providing the first voltage and allows a specific capacitor of the capacitor group to enter a floating state. In the third period, a second voltage, which is lower than the first voltage, is provided to the additional capacitor.
Another notable patent is the "Successive Approximation Register Analog-to-Digital Converter and Control Method Thereof." This invention features a first capacitor group, a second capacitor group, and a control circuit. Each capacitor group consists of multiple capacitors connected to a common node. During the sampling mode, the control circuit supplies an analog signal to the first capacitor group and a first voltage to the common node and the second capacitor group. In this mode, the control circuit eventually stops providing the first voltage and instead supplies a second voltage to the second capacitor group. During the data converting mode, the control circuit sequentially reads the voltage values of the capacitors in the first capacitor group, floating one capacitor from the second capacitor group each time a specific capacitor's voltage is read.
