Title: Lu-Yueh Hsu: Innovator in Circuit Design

Introduction

Lu-Yueh Hsu is a talented inventor based in Sinjhuang, Taiwan. She has made significant contributions to the field of circuit design, holding 2 patents that showcase her innovative spirit and technical expertise. Her work primarily focuses on enhancing the functionality and efficiency of electronic devices.

Latest Patents

One of her latest patents is a duty cycle detecting circuit for pulse width modulation (PWM). This circuit includes a clock generating circuit, a sampling circuit, and a calculation circuit. The clock generating circuit is responsible for generating a clock signal. The sampling circuit receives a PWM signal and the clock signal, samples the PWM signal based on the clock signal, and generates a sampling signal. The calculation circuit then calculates the duty cycle of the PWM signal based on the sampling signal.

Another notable patent is a chip structure capable of smoothing the slope of a signal during conversion. This invention is particularly suitable for a DC motor embedded in portable electronic devices. The DC motor adjusts the focal distance of a digital camera installed within the device. The chip structure comprises an input terminal, a first converter, a control unit, a second converter, an amplifier circuit, and an output terminal. The input terminal receives a first digital signal, while the first converter converts it into an analog signal. The control unit elongates the transform time of the analog signal, and the amplifier circuit amplifies this elongated signal. Finally, the second converter converts the elongated analog signal back into a second digital signal, which is then output through the output terminal.
