摘要： A system on a package (SOP) can include a galvanic isolator. The galvanic isolator can include an input stage configured to transmit an input RF signal in response to receiving an input modulated signal. The galvanic isolator can also include a resonant coupler electrically isolated from the input stage by a dielectric. The resonant coupler can be configured to filter the input RF signal and transmit an output RF signal in response to the input RF signal. The galvanic isolator can further include an output stage electrically isolated from the resonant coupler by the dielectric. The output stage can be configured to provide an output modulated signal in response to receiving the output RF signal.

摘要： Isolation circuits for digital communications and methods to provide isolation for digital communications are disclosed. An example isolation circuit includes an isolation barrier, a burst encoder in a first circuit, and an edge pattern detector in a second circuit. The example isolation barrier electrically isolates the first circuit from the second circuit. The example burst encoder generates a first pattern in response to receiving a rising edge on an input signal and generates a second pattern in response to receiving a falling edge on the input signal. The example edge pattern detector detects the first pattern or the second pattern received from the burst encoder via the isolation barrier, sets an output signal at a first signal level in response to detecting the first pattern, and sets the output signal at a second signal level in response to detecting the second pattern.

Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module. An artificial magnetic conductor surface is positioned adjacent the backside of each NFC coupler to reflect back side electromagnetic energy with a phase shift of approximately zero degrees.

摘要： A method and device for providing isolated power transfer to a low-power load across a capacitor of a series resonance circuit are shown. The method includes comparing an output voltage received via a feedback loop with a desired output voltage. Responsive to determining that the output voltage is not equal to the desired output voltage, the method determines a sub-harmonic order of the resonant frequency of the series resonance circuit to use as a switching frequency and switches the series resonance circuit at substantially the determined subharmonic order of the resonant frequency.

摘要： In described examples, a first isolation element electrically isolates a first circuit from a second circuit and passes AC signals between the first circuit and the second circuit. A second isolation element electrically isolates the first circuit from the second circuit and passes AC signals between the first circuit and the second circuit. A ground of the second circuit electrically floats relative to a ground of the first circuit, so that a digital signal is able to pass from the second circuit through a third isolation element to the first circuit. A supply voltage generation device converts AC signals from the first isolation element and the second isolation element into at least one DC voltage to power the second circuit.
