摘要： A controller for a semiconductor switch is described that includes a transmitter and a receiver that communicate across galvanic isolation using an inductive coupling. An example controller includes first circuitry referenced to a first reference potential, second circuitry referenced to a second reference potential and galvanically isolated from the first circuitry, and an inductive coupling galvanically isolating the first circuitry and the second circuitry. The inductive coupling includes a first winding referenced to the first reference potential and a second winding referenced to the second reference potential, wherein the first circuitry includes signal reception circuitry coupled to the inductive coupling, wherein the signal reception circuitry includes one or more signal receivers coupled to the first winding to receive signals transmitted over the inductive coupling.

摘要： A signal transmission system for communicating across galvanic isolation includes a magnetic coupling having a transmitter-side inductor and a receiver-side inductor. The transmitter is coupled to the transmitter-side inductor, is referenced to a first potential, and includes a pulse generator coupled to output to the transmitter-side inductor a first state representation that represents a first logic state with multiple transitions, and a second state representation that represents a second logic state with multiple transitions. The pulse generator in outputting the first state representation is coupled to output a first information portion that includes the multiple transitions of the first state representation, and a first initial delay portion having a duration longer than a duration of the multiple transitions of the second state representation.

摘要： An analog receiver frontend includes a first amplification circuit coupled to receive an input signal. The first amplification stage is coupled to amplify a difference between the input signal and a threshold to generate the first signal. A second amplification circuit is coupled to receive the first signal from the first amplification circuit. The second amplification circuit is coupled to amplify the first signal to generate a second signal. An output circuit is coupled to receive the second signal from the second amplification circuit. The output circuit is coupled to output a recovered signal. The recovered signal is a pulse waveform of high and low sections. An input hysteresis circuit is coupled to the output circuit to receive the recovered signal and generate a hysteresis signal. One or both of the input signal and the threshold are level shifted by the hysteresis signal in response to the recovered signal.
