Latest Patents

One of Hsu's latest patents is a "Power processing interface for passive radio frequency identification system." This invention provides a power processing interface that includes a resonance circuit for inducing a first signal transmitted from a terminal as an AC voltage. It features a first rectifier circuit that converts the AC voltage into a DC voltage, along with a filter circuit that generates an operating voltage in response to the DC voltage. Additionally, it includes a voltage-detecting circuit for monitoring the magnitude of the operating voltage and a second rectifier circuit. The voltage-clamping modulation circuit controls the conduction of the second rectifier circuit to bypass excessive current, ensuring the radio frequency identification system operates normally.

Another significant patent is the "Method for calibrating parameter of integrated circuit." This method utilizes an external device to calibrate an analog control parameter of an internal analog circuit in the integrated circuit. The external device detects whether the parameter is beyond a predetermined range and calibrates it accordingly. This process is repeated until the parameter is within the acceptable range, at which point the calibrated value is stored in the non-volatile memory of the integrated circuit.
