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： An optical coupler having an optical transmitter and an optical receiver are disclosed. The optical transmitter receives a logic signal to be transmitted to a circuit connected to the optical receiver and a photo emitter for generating a light signal having an intensity related to the states of the logic signal. The optical receiver includes a photodetector assembly, a hold circuit, a threshold generating circuit, and a signal generator. The photodetector assembly receives the light signal and generates a photo signal having an amplitude related to that of the light signal. The hold circuit stores a potential related to the maximum amplitude of the photo signal during a preceding time period. The threshold generating circuit generates a high threshold signal related to the stored potential. The signal generator generates an output logic signal that has first and second states that change state when the photo signal crosses the high threshold.
