Title: Innovations by Chunwei Chang in Power-Efficient Circuit Design

Introduction

Chunwei Chang is an accomplished inventor based in Sunnyvale, CA. He has made significant contributions to the field of energy-efficient circuit design. His innovative work focuses on creating circuits that optimize power consumption while maintaining performance.

Latest Patents

Chunwei Chang holds a patent for a power-efficient biasing circuit. This invention describes energy-efficient timing circuits that include a biasing circuit designed to provide a control bias current to a voltage-controlled oscillator (VCO). The biasing circuit is capable of switching between a normal-power operating mode and a reduced-power operating mode. During the normal-power mode, it generates a control voltage that represents the desired control bias current for the VCO. By storing this control voltage using a device such as a capacitor, much of the biasing circuit can be turned off during the reduced-power mode, leading to significant energy savings.
