Introduction

Winway Chen is an inventor based in San Jose, California. His patent work concerns power regulation and fast transient current sensing. He is associated with Alpha and Omega Semiconductor International LP.

Latest Patents

Chen is credited with 1 patent: “High Power Fast Transient Response Linear Current Sensing Topology.” The patent describes a pole-zero-balanced power-switching regulation system intended for high-power, high-frequency applications.

In one example, a trans-inductor voltage regulator (TLVR) has at least two phases, each with a current-inducing circuit. A second-order current-sensing circuit measures the current in each phase. The described transfer functions are designed so that corresponding poles and zeros effectively cancel, keeping the gain and phase difference close to zero. This approach may enable fast transient current measurement in the TLVR.

Career Highlights

Chen’s listed invention focuses on improving current measurement in power-regulation systems. Its design combines a multiphase TLVR with a second-order sensing circuit to support responsive operation in demanding applications.

Collaborations

Chen’s listed coworkers include Sitthipong Angkititraku and Li Jiang. The available information identifies them as colleagues but does not specify their roles in the patent.
