Abstract: Improvements over existing data collection interfaces disclosed herein include, among other things, additional logic blocks (and associated timers, state machines, and registers) to off-load data collection and data processing prior to waking a microprocessor from a sleep mode. For example, an improved data collection interface collects a predetermined number of sensor values from a sensor while maintaining active a single communication session with the sensor over a pin of the interface. The microprocessor remains in the sleep mode for an entire duration of the single communication session. The data collection interface can reduce the likelihood of false starts of the microprocessor by using the logic blocks to verify that data meet preconditions prior to interrupting the microprocessor. The data collection interface can reduce the overall power consumption of a chip in which the microprocessor is integrated by a factor of at least about 2× (i.e., 50% reduction in power consumption).

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: A relaxation oscillator can provide a smaller and cheaper alternative to a crystal oscillator circuit in a wide variety of applications. A sawtooth relaxation oscillator can include overshoot error integration. Separate and distinct oscillator capacitor charging, overshoot error integration, and reset phases can be provided using separate comparators for first and second oscillation capacitors. Potential advantages can include high accuracy high-frequency clock, convenient trimming during initial calibration, clock frequency stability over temperature and time, fast startup with low overshoot, high power supply rejection, low power, or low noise/jitter. The oscillator can charge an oscillation capacitor up to a target voltage, then interrupt charging before beginning an error integration phase that adjusts the target voltage by integrating an overshoot error of a voltage on the oscillation capacitor. After completing the overshoot error integration, the voltage on the oscillation capacitor can be reset. The techniques described are believed to be capable of improving clock frequency accuracy and other characteristics.

Abstract: An “all-digital” operational amplifier architecture, that does not have the constraint of maintaining devices in their saturation region, can leverage the high speed achievable by deeply scaled technology to replace traditional linear current referenced continuous-time operational amplifier circuits with CMOS-like dynamic circuits that require no referencing structure, have no static power consumption, and are compatible with ultra-low supply voltages. Techniques are described to replace analog continuous-time linear operational amplifier input and output stages by a discrete-time comparator circuit, e.g., CMOS-style, and a switched capacitor charge pump circuit, respectively.

Abstract: Embodiments of the present disclosure propose analog-to-digital conversion (ADC) systems particularly suitable for Light Detection and Ranging (LIDAR) implementations. An exemplary proposed ADC system is configured to determine whether an absolute value of an analog value is greater than a threshold, and, upon positive determination, assign a predetermined digital value as a digital value corresponding to the analog value, without proceeding with the analog-to-digital conversion of the analog value. Because the ADC system only proceeds with the analog-to-digital conversion, using an ADC, when the input analog value is smaller than the threshold, and otherwise the input analog value is simply assigned some predefined digital value, design complexity and power consumption of the system may be significantly reduced, compared to conventional ADCs used in LIDAR applications.

Abstract: An image sensor can respond to light either linearly or logarithmically in order to achieve flexible and high contrast performance. This is made possible by using a programmable lookup table, or an array of numbers, that represents control parameter values of the image sensor. The control parameter values in the lookup table are programmable and could be kept constant, increase linearly, or non-linearly, between consecutive indexes. Photodiode control circuitry is used to adapt the response of the photodiodes in the image sensor depending on the lighting impacting upon the image sensor.

Abstract: The sensor interface IC measures or calibrates a target resistance to be used as a gain resistor for a TIA amplifier in the sensor interface IC. One or more excitation currents are generated in response to different specified excitation voltages that are applied to an external calibration resistor having a specified calibration resistance value. Response voltages are measured across the target resistor, respectively in response to the corresponding different one or more excitation currents. The resistance value of the target resistor is determined using a difference between the measured response voltages, a difference between the specified excitation voltages, and the specified calibration resistance value.

Abstract: A magnetic device may include a magnetic structure, a device structure, and an associated circuit. The magnetic structure may include a patterned layer of material having a predetermined magnetic property. The patterned layer may be configured to, e.g., provide a magnetic field, sense a magnetic field, channel or concentrate magnetic flux, shield a component from a magnetic field, or provide magnetically actuated motion, etc. The device structure may be another structure of the device that is physically connected to or arranged relative to the magnetic structure to, e.g., structurally support, enable operation of, or otherwise incorporate the magnetic structure into the magnetic device, etc. The associated circuit may be electrically connected to the magnetic structure to receive, provide, condition or process of signals of the magnetic device.

Abstract: A system and method for operating a high dynamic range analog front-end receiver for long range LIDAR with a transimpedance amplifier (TIA) include a clipping circuit to prevent saturation of the TIA. The output of the clipping circuit is connected via a diode or transistor to the input of the TIA and regulated such that the input voltage of the TIA remains close to or is only slightly above the saturation threshold voltage of the TIA. The regulation of the input voltage of the TIA can be improved by connecting a limiting resistor in series with the diode or transistor. A second clipping circuit capable of dissipating higher input currents and thus higher voltages may be connected in parallel with the first clipping circuit. A resistive element may be placed between the first and second clipping circuits to further limit the input current to the TIA.
