    摘要： According to one embodiment, there is provided a method of reducing the amount of power consumed by a galvanic isolator. A transmitter transmits a wake-up signal to a receiver located across an isolation medium when the transmitter is ready or preparing to transmit data or power signals to a receiver, which is operably connected to a sensing circuit. The sensing circuit receives the wake-up signal through the isolation medium, which may be operably connected to and powered substantially continuously or intermittently by a first power source. In response to the sensing circuit receiving the wake-up signal, the receiver is powered up from a sleep mode to an operating mode. After a period of time tRDY has passed since the wake-up signal was transmitted, a signature pattern is transmitted from the transmitter to the sensing circuit through the isolation medium. Next, the sensing circuit or the receiver verifies the validity of the signature pattern. If the signature pattern is determined at to be valid, the receiver is enabled to receive the data or power signals from the transmitter. The transmitter then transmits the data or power signals from the transmitter through the isolation medium to the receiver.

    摘要： According to one embodiment, there is provided a high voltage drive circuit comprising drive and sense electrodes formed substantially in a single plane. The device effects signal transfer between drive and receive circuits through the drive and sense electrodes by capacitive means, and permits high voltage devices, such as IGBTs, to be driven thereby without the use of high voltage transistors, thereby eliminating the need to use expensive fabrication processes such as SOI when manufacturing high voltage gate drive circuits and ICs. The device may be formed in a small package using, by way of example, using CMOS or other conventional low-cost semiconductor fabrication and packaging processes.

    摘要： According to one embodiment, there is provided a semiconductor digital communication device comprising communication drive and sense electrodes formed in a single plane, where the electrodes have relatively high sidewalls. The relatively high sidewalls permit low electrical field densities to be obtained in the sense and drive electrodes during operation, and further permit very high breakdown voltages to be obtained between the electrodes, and between the drive electrode and an underlying ground plane substrate. The device effects communications between drive and receive circuits through the drive and sense electrodes by capacitive means, and in a preferred embodiment is capable of effecting relatively high-speed digital communications. The device may be formed in a small package using, by way of example, CMOS or other semiconductor fabrication and packaging processes.
