Latest Patents

One of his latest patents is a circuit capable of automatically calibrating a resonance frequency of an antenna and method thereof. This invention includes an antenna, a switch, a conversion unit, a count comparator, and a capacitor array. The switch is coupled to the antenna and is designed to be turned on and off according to a pulse. The antenna generates the resonant frequency based on the switch's operation. The conversion unit generates a clock according to a signal with the resonant frequency. The count comparator counts a number generated by a reference clock during a period of the clock and compares the pulse number with a predetermined value to generate an adjustment signal. The capacitor array adjusts its capacitance according to the adjustment signal.

Another significant patent is a voltage-controlled capacitor circuit and related circuitry with diode and MOS varactors. This circuit includes a metal-oxide semiconductor (MOS) varactor, a diode varactor, and/or a capacitor with fixed capacitance. These components are electrically connected in parallel or in series to form a capacitor with a preferred characteristic of voltage-controlled capacitance.
