发明名称 Single differential transformer core
摘要 An integrated circuit is disclosed. The integrated circuit includes a primary coil. The integrated circuit also includes a first secondary coil that acts as a first transformer with the primary coil. The integrated circuit further includes a second secondary coil that acts as a second transformer with the primary coil. The primary coil, the first secondary coil and the second secondary coil have a layout on the integrated circuit to minimize coupling between the first secondary coil and the second secondary coil.
