Latest Patents

Among his latest innovations, Liu has developed a patent titled "Method of operating analog-to-digital converter by reversed switching technique." This involves a method where, during the first conversion period, a comparator generates a first comparison result. A first selection circuit then switches a voltage output to a first capacitor in a larger capacitor array, while a second selection circuit does the same for a second capacitor in another array. In the subsequent conversion period, a second comparison result is generated, leading to a switch back to the initial configurations.

Another notable patent is the "Analog-to-digital converter capable of reducing nonlinearity and method of operating the same." This invention incorporates a switch circuit, two capacitor arrays, and a comparator. During the first sampling period, the switch circuit couples the first capacitor array to the first input terminal of the comparator. In a second sampling period, the connections are reversed, allowing for improved data accuracy and reduced nonlinearity.
