Abstract: Embodiments of the present disclosure provide ADCs particularly suitable for PDAF image sensors, which ADCs may have an increased speed and/or reduced design complexity and power consumption compared to conventional implementations. An example ADC for a PDAF image sensor is configured to implement modified SAR techniques which reduce the number of bit trials required for conversion, and enable increased number of samples in a row-conversion time period of the image sensor. The ADC may implement the modified SAR techniques in combination with CMS in pixel readout signal chain, which may reduce noise without a proportionate increase in ADC sample rate.

Abstract: This disclosure relates to fractional-N phase-locked loops. A digital filter can filter out quantization noise from a modulator. Separate paths can process an integer part associated with an output signal of the digital filter and a fractional part associated with the output signal of the digital filter. The separate paths can be combined in the fractional-N phase-locked loop, for example, as a weighted sum.

Abstract: The disclosed technology generally relates to electrical overstress protection devices, and more particularly to electrical overstress monitoring devices for detecting electrical overstress events in semiconductor devices. In one aspect, a device configured to monitor electrical overstress (EOS) events includes a pair of spaced conductive structures configured to electrically arc in response to an EOS event, wherein the spaced conductive structures are formed of a material and have a shape such that arcing causes a detectable change in shape of the spaced conductive structures, and wherein the device is configured such that the change in shape of the spaced conductive structures is detectable to serve as an EOS monitor.

Abstract: A stage, suitable for use in an analog to digital converter or a digital to analog converter where the stage comprises a plurality of slices that can be operated together to form a composite output, can have reduced thermal noise, whilst each slice on its own has sufficiently small capacitance to respond quickly to changes in digital codes applied to the slice. This allows a fast conversion to be achieved without loss of noise performance.

Abstract: Disclosed herein are systems and methods for performing DC offset correction of a video signal received over an AC-coupled video link. In one aspect, a transmitter is configured to compute, and provide to a receiver, metadata indicative of a statistical characteristic (e.g., an average or a sum of values) for a group of active pixels of a video signal acquired by a camera. The receiver is configured to compute an analogous statistical characteristic on the video signal received over an AC-coupled video link, and to perform DC offset correction by modifying one or more values of the received video signal based on a comparison of the statistical characteristic computed by the receiver and the one computed by the transmitter and indicated by the received metadata.

Abstract: Amplifier systems for driving a wide range of loads are provided herein. In certain embodiments, an amplifier system includes a voltage output amplifier and a current output amplifier that are electrically coupled in parallel with one another between an input terminal and an output terminal. The amplifier system further includes a control circuit operable to control whether or not the voltage output amplifier and/or current output amplifier drive the output terminal.

Abstract: A monolithic vapor chamber heat dissipating device uses a phase change liquid and one or more wicks to dissipate heat from a heat-generating system. The phase change liquid and one or more wicks may be directly coupled to the heat-generating system, or may be coupled to an intermediate evaporator substrate. The phase change liquid vaporizes as it absorbs heat from the heat-generating system. When the vapor rises and encounters a condenser substrate, the vapor condenses and transfers the heat to the condenser substrate. The condensed vapor is drawn by gravity and the one or more wicks to the phase change liquid coupled to the heat-generating system.

Abstract: The present disclosure relates to a digital-to-analog converter (DAC) which includes a resistor string and a transfer function modification circuit. The transfer function modification circuit may be a calibration circuit for calibrating the DAC, The calibration circuit may include a plurality of current sources, which may be current DACs. Each of the current DACS inject current into, or drain current from, a respective node of the resistor string, in order to correct for voltage errors. The injected currents may be positive or negative, depending on the voltage error. The current DACs are controlled by trim codes, which are set dependent on the measured or simulated voltage errors for a given resistor string.

Abstract: The subject disclosure provides for utilizing pulse width modulation (PWM) signaling to influence a closed loop of a shunt boost controller and reduce an imbalance of a load. The imbalance reduction helps reduce remanence of a current transformer (CT) and thereby prevent saturation of the CT. A shunt boost controller provides the control signal to control flow of current to the load. A feedback network provides a feedback signal to the shunt boost controller based on a direct current (DC) voltage and causes a power switch circuit to turn on when a magnitude of the feedback signal exceeds a threshold magnitude. The PWM generator supplies a PWM signal to cause the control signal to be provided more symmetrical to the power switch circuit and causes the power switch circuit to turn on more frequently with the control signal to reduce the imbalance of the load.
