Title: Ziyan Wang and the Low-Leakage Multiplexer

Introduction

Ziyan Wang is an inventor based in Sunnyvale, California, and is associated with Apple Inc. His patent work includes a circuit design intended to reduce leakage in a multiplexer.

Latest Patents

Wang is named on one patent, titled “Low Leakage Multiplexer.” The invention describes a multiplexer with multiple switch circuits connecting respective input nodes to a shared output node. Each circuit uses two series-connected switch elements and an intermediate node, along with a third switch element connected to a buffer.

When a switch circuit is selected, its two series elements activate to establish a path from the input to the output, while the third element remains inactive. When the circuit is not selected, the series elements deactivate and the third element activates, driving a buffered voltage to the intermediate node. This arrangement is designed to limit leakage through unselected switch circuits. Wang’s listed patent portfolio comprises 1 patent.

Career Highlights

Wang’s recorded invention reflects work in electronic circuit design, particularly multiplexer switching and leakage management. He is associated with Apple Inc., though the supplied information does not specify his role or employment history.
