    Abstract: A capacitive element has its terminals coupled together by two thyristors electrically in antiparallel. The discharge of the capacitive element is controlled by the application of a gate current to one thyristor of the two thyristors which is in a reverse-biased state in response to a voltage stored across the terminals of the capacitive element. The reverse-biased thyristor responds to the applied gate current by passing a leakage current to discharge the stored voltage.

    Abstract: Disclosed herein is an ambient light sensor formed by a substrate, and an inner central area defined on the substrate, and a concentric polygonal shape defined on the substrate about the inner central area. The concentric polygonal shape is defined by concentric polygonal isolation regions and spoke shaped isolation regions extending through respective corners of the concentric polygonal isolation regions to the inner central area to thereby divide the concentric polygonal shape into a plurality of concentric polygonal regions, with each of the plurality of concentric polygonal regions divided into a plurality of trapezoidal sections. A plurality of photodiodes ae formed on the substrate such that each of the plurality of trapezoidal sections contains at least one photodiode. A color filter is applied to the plurality of trapezoidal sections and their respective photodiodes to thereby form a plurality of color channels.

    Abstract: A controller chip includes processing circuitry configured to process received samples by estimating trend functions from the samples, subtracting the trend functions from the samples to produce de-trended samples, performing a mathematical transform on the de-trended samples to produce frequency bins. The frequency bins may correspond to unwanted resonance movement of a movable mirror associated with the received samples. The processing circuit further generates an error function from the frequency bins. The error function can be used to generate correction signals for the movable mirror that serve to minimize the error function.

    Abstract: Mirror control circuitry described herein is for controlling a first micro-mirror of a micro-mirror apparatus that scans across a target area in a scan pattern. The mirror control circuitry includes a processor that determines a mechanical angle of the first micro-mirror for a given instant in time during scanning of the first micro-mirror between upper and lower rotational limits, the mechanical angle being such to maintain the scan pattern as being uniform while the micro-mirror apparatus scans across the target area between the upper and lower rotational limits. The processor also generates a driving signal for the first micro-mirror as a function of the determined mechanical angle for the first micro-mirror at the given instant in time.

    Abstract: Disclosed herein is a control circuit for a movable mirror. The control circuit includes driving circuitry configured to drive the movable mirror with a drive signal to effectuate oscillating of the movable mirror, opening angle determination circuitry configured to determine an opening angle of the movable mirror, and amplitude control circuitry. The amplitude control circuitry is configured to a) first cause the driving circuitry to generate the drive signal as having an upper threshold drive amplitude, and b) then later cause the driving circuitry to generate the drive signal as having a nominal drive amplitude, as a function of the opening angle of the movable mirror being equal to a desired opening angle.

    Abstract: Disclosed herein is a circuit for determining failure of a movable MEMS mirror. The circuit includes an integrator receiving an opening angle signal representing an opening angle of the movable MEMS mirror, and a differentiator receiving the opening angle signal. A summing circuit is configured to sum the integrator output and the differentiator output. A comparison circuit is configured to determine whether the sum of the integrator output and differentiator output is not within a threshold window. An indicator circuit is configured to generate an indicator signal indicating that the movable MEMS mirror has failed based on the comparison circuit indicating that the sum of the integrator output and differentiator output is not within the threshold window.

    Abstract: Pins on an RFIC package carry RF signals between the package and a PCB. A first capacitor is coupled between a selected pin of the RFIC package near the pins carrying the RF signals and a radio-frequency ground on the PCB. A coupling between the RFIC package and the PCB is modeled, and includes modeling of the pins of interest and at least one parasitic element of the coupling. A capacitance of the first capacitor is selected based on the modeling to obtain desired performance at selected operational frequencies. A second capacitor may be coupled between the selected pin a radio frequency ground of the RFIC package. An inductor may be coupled in parallel across the first capacitor.
