Title: The Innovations of Hou-Kuan Sung

Introduction

Hou-Kuan Sung is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of digital technology, holding a total of 3 patents. His work primarily focuses on advancements in digital video broadcasting and signal processing.

Latest Patents

One of his latest patents is a digital video broadcast receiver. This innovative device includes a frequency synthesizer, multiple frequency dividing-phase shifting circuits, an antenna, and several signal processing modules. The frequency synthesizer is responsible for synthesizing a first frequency signal. The frequency dividing-phase shifting circuits perform operations on this signal to generate various first and second signals, which are orthogonal to each other. The antenna captures radio frequency signals, while the signal processing modules extract different sub-band signal components based on the generated signals.

Another significant patent is a signal generating circuit that features a filtering circuit coupled between level shifters. This circuit includes a detecting circuit, a charge pump, and two level shifters. The detecting circuit outputs a signal based on a reference and oscillating signal. The charge pump then generates a first output signal through charging or discharging operations. The first level shifter adjusts the voltage level of this output, leading to a second output signal. The filtering circuit produces a filtered control signal, which is further adjusted by the second level shifter before being used by a controllable oscillator to output the oscillating signal.
