Abstract: Apparatus and methods provide predistortion for a phased array. Radio frequency (RF) sample signals from phased array elements are provided along return paths and are combined by a hardware RF combiner. Phase shifters are adjusted such that the RF sample signals are phase-aligned when combined. Adaptive adjustment of predistortion for the amplifiers of the phased array can be based on a signal derived from the combined RF sample signals.

Abstract: Aspects of this disclosure relate to a receiver for a light detection and ranging system. The receiver includes a transimpedance amplifier that is operable in a linear mode for a range of power of light received by the receiver. The receiver can provide information about amplitude of the light outside of the range of power of the light for which the transimpedance amplifier operates in the linear mode. This information can be useful, for example, in identifying an object from which light received by the receiver was reflected.

Abstract: Current measurement apparatus comprises a measurement arrangement and a signal source. The measurement arrangement is configured to measure a current signal drawn by a load. The signal source is operative to apply a reference input signal to the measurement arrangement whereby an output signal from the measurement arrangement comprises a load output signal corresponding to the load drawn current signal and a reference output signal corresponding to the reference input signal. The signal source comprises a current multiplier which defines first and second current paths and is configured such that: the first path carries a multiplier input current signal; the second path carries a multiplier output current signal which determines the reference input signal and which corresponds to the multiplier input current signal multiplied by a multiplier value determined by the current multiplier; and the multiplier input current signal and the multiplier output current signal are carried on their respective paths in a same direction relative to a power supply voltage. Power drawn through the second path as divided by the multiplier value is less than the power drawn through the first path.

Abstract: Disclosed herein are systems and techniques for content protection over synchronous data networks. For example, a method of communicating content protected data may include providing link synchronization information over a link of a synchronous bus, and providing content protected data over the link of the synchronous bus. The content protected data may be protected in accordance with the High-Bandwidth Digital Content Protection (HDCP) specification or the Digital Transmission Content Protection (DTCP) specification, for example.

Abstract: Aspects of the present disclosure relate to decoding the output of a multi-turn magnetic sensor using a successive approximation technique to detect a number of turns of a magnetic target. A decoder circuit can decode a turn count of the multi-turn magnetic sensor by obtaining measurements at nodes that are determined from values of previous measurements.

Abstract: The present disclosure provides a pulse generator which generates a pulse train by mixing pulses of a first clock having a first frequency, with pulses of a second clock having a second frequency. Over a predefined time period, the combination of pulses results in a pulse train having an effective frequency which is between the first and second frequencies. A multiplexer is used to select which of the first and second clocks should be provided to the output. Depending on the desired target frequency, the multiplexer is controlled to mix differing amounts of pulses from the first and second clocks. A multiplexer is controlled by a control signal, which is generated using combinatorial logic using the first clock as an input. The pulse generator may be used, for example, as a clock for a charge pump.

Abstract: A continuous-time sampler has series-connected delay lines with intermediate output taps between the delay lines. Signal from an output tap can be buffered by an optional voltage buffer for performance. A corresponding controlled switch is provided with each output tap to connect the output tap to an output of the continuous-time sampler. The delay lines store a continuous-time input signal waveform within the propagation delays. Controlling the switches corresponding to the output taps with pulses that match the propagation delays can yield a same input signal value at the output. The continuous-time sampler effectively “holds” or provides the input signal value at the output for further processing without requiring switched-capacitor circuits that sample the input signal value onto some capacitor. In some cases, the continuous-time sampler can be a recursively-connected delay line. The continuous-time sampler can be used as the front end sampler in a variety of analog-to-digital converters.

Abstract: There is provided an active-pixel image sensor that uses a method of offsetting and interleaving to increase its resolution. In a basic configuration of the active-pixel image sensor, light from one optical transmitter is diffracted to create one diffraction pattern, and then light from another optical transmitter is diffracted to create another diffraction pattern. Light from further optical transmitters may also be diffracted to create further diffraction patterns sequentially after that. These diffraction patterns are offset from one another and then interleaved using time division multiplexing so as to create a single pixel output that has higher resolution than is feasible with an active-pixel image sensor that only utilizes one optical transmitter per pixel or that does not use diffraction patterns to create a larger field of view.
