Abstract: An apparatus includes first and second oscillator circuits. A transformer has a primary winding coupling the first oscillator circuit to the second oscillator circuit and a secondary winding. A first outgoing communications circuit is coupled to the second oscillator circuit and drives an amplitude modulated data signal thereto. A first incoming communications circuit is coupled to the primary winding of the transformer. A second outgoing communications circuit is coupled to the secondary winding drives an amplitude modulated data signal thereto. A second incoming communications circuit is coupled to the secondary winding. The secondary winding is magnetically coupled with the primary winding so the secondary winding receives an output power and an incoming data transmission based upon the amplitude modulated data signal, and so the primary winding receives an incoming high speed data transmission based upon the amplitude modulated data signal.

Abstract: An oscillator circuit includes a total of N (N≥2) class-D oscillator circuits stacked together between a supply voltage node and a reference voltage node. The output ports of adjacent class-D oscillator circuits in the disclosed oscillator circuit are coupled together by capacitors to ensure frequency and phase synchronization for the frequency signals generated by the class-D oscillator circuits. Compared with a reference oscillator circuit formed of a single class-D oscillator circuit, the oscillation amplitude of each of the class-D oscillator circuits in the disclosed oscillator circuit is 1/N of that of the reference oscillator circuit, and the current consumption of the disclosed oscillator circuit is 1/N of that of the reference oscillator circuit.

Abstract: An oscillator is coupled to a first side of a galvanic barrier for supplying thereto an electric supply signal. The oscillator is configured to be alternatively turned on and off as a function of a PWM drive signal applied thereto. A receiver circuit coupled to the galvanic barrier receives therefrom a PWM power control signal. A signal reconstruction circuit coupled between the receiver circuit block and the oscillator provides to the oscillator a PWM drive signal reconstructed from the PWM power control signal. The signal reconstruction circuit includes a PLL circuit coupled to the receiver circuit block and configured to lock to the PWM control signal from the receiver circuit block. A PLL loop within the PLL circuit is sensitive to the PWM drive signal applied to the oscillator. The PLL loop is configured to be opened as a result of the power supply oscillator being turned off.

Abstract: Power and data are transmitted via a transformer including primary side and secondary side. A primary side signal is generated by coupling a first oscillator signal modulated with a data signal with a second oscillator signal that is selectively switched on and off. At the secondary side a secondary signal is generated. A demodulator demodulates the secondary signal to recover the data signal. A rectifier processes the secondary signal to recover a power supply signal controlled by switching on and off the second oscillator.

Abstract: A DC-DC converter includes a transformer having primary and secondary windings, a power oscillator applying an oscillating signal to the primary winding to transmit a power signal to the secondary winding, a rectifier obtaining an output DC voltage by rectifying the power signal at the secondary winding, and comparison circuitry generating an error signal representing a difference between the output DC voltage and a reference voltage value. A transmitter connected to the secondary winding performs an amplitude modulation of the power signal at the secondary winding to transmit an amplitude modulated power signal to the primary winding, the amplitude modulation based upon the error signal and modulating a stream of data to the primary winding. A receiver coupled to the primary winding demodulates the amplitude modulated power signal to recover the error signal and the stream of data. An amplitude of the oscillating signal is controlled by the error signal.
