Semiconductor Transformers    

A semiconductor transformer in which all parts of the transformer are made of semiconductor materials.

Overview

The technology relates to a “semiconductor transformer” totally incorporated into integrated semiconductor electronic circuits. It is derived from the coreless planar transformer concept but it does not need metal conductors as transformer windings. The windings are made of highly doped semiconductor paths.

The benefits arising from this invention include possibility of full circuit integration; reduction in manufacturing costs, stray components and circuit noise; improvement in power density and system compactness.

Primary Application of the Technology

Any electronic circuits required magnetic transformers for isolation, etc functions.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)

This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass 528: Passive components in ICs
Subclass 531: Including inductive element
