    Abstract: A resonant power transfer system includes resonant circuitry (26) including an inductor coil (59) and a resonant capacitor (51) coupled to a first terminal (27) of the inductor coil, wherein the inductor coil and the resonant capacitor resonate to produce an excitation signal (IS) and a state variable signal (VCS1). Sub-sampling circuitry (30) samples first and second points of the state variable signal at a rate which is substantially less than the RF frequency of the state variable signal. Information recovery circuitry (32) produces a state variable parameter signal representing a parameter (A) of the state variable signal from information in the first and second sampled points. Control circuitry (38) produces a first control signal in response to the state variable parameter signal. Detection and optimization circuitry (41) produces a second control signal in response to the state variable parameter signal. Voltage regulation circuitry (45) produces a regulated supply voltage in response to the first control signal. Switching inverter circuitry produces the excitation signal in response to the regulated supply voltage and the second control signal.

    Abstract: An inductive structure includes a power coil and a data coil. The data coil is substantially centered within the power coil. A first portion of the data coil conducts current in a first direction. A second portion of the data coil conducts current in a second direction opposite the first direction. The first portion of the data coil is connected at a node to the second portion of the data coil. The node is coupled to a ground.

    CPC classification number: H03L7/091

    Abstract: A sampling phase locked loop (PLL) circuit includes a pull-up/down buffer configured to convert an oscillator reference clock into a square wave sampling control signal input to a sampling phase detector. The buffer circuit is configured to reduce power by controlling the switching of the pull-up and pull-down transistors (and thereby the transitions of the sampling control signal) so that the transistors are not on at the same time.

    Abstract: In a first inductive structure, a first data coil includes: a first portion for conducting a first common mode current in a first direction; and a second portion for conducting a second common mode current in a second direction opposite the first direction. The first and second portions of the first data coil are connected at a first node. In a second inductive structure, a second data coil includes: a first portion for conducting a third common mode current in the first direction; and a second portion for conducting a fourth common mode current in the second direction. The first and second portions of the second data coil are connected at a second node galvanically isolated from the first node. The first, second, third and fourth common mode currents are induced by a common mode transient.

    Abstract: Circuits for controlling a plurality of LEDs connected in series are disclosed herein. The circuit includes a plurality of switches, wherein each switch is connectable between the anode and cathode of one of the plurality of LEDs. Each of the switches has a first state wherein current does not pass through the switch and a second state wherein current passes through the switch. The circuit also includes an input for receiving data to program the switches and a data line for transferring data between a circuit controlling second LEDs that are connected in parallel with the first LEDs and the circuit. In addition, the circuit includes a data output for transferring data to other circuits controlling third LEDs that are connected in series with the first LEDs.
