  • Patent number: 10050640
    Abstract: Data weighted averaging of a thermometric coded input signal is accomplished by controlling the operation of a crossbar switch matrix to generate a current cycle of a data weighted averaging output signal using a control signal generated in response to feedback of a previous cycle of the data weighted averaging output signal.

  • Patent number: 10048488
    Abstract: Disclosed herein is a circuit for determining failure of a movable MEMS mirror. The circuit includes a mirror position sensor associated with the movable MEMS mirror and that generates an analog output as a function of angular position of the movable MEMS mirror. An analog to digital converter converts the analog output from the mirror position sensor to a digital mirror sense signal. Failure detection circuitry calculates a difference between the digital mirror sense signal at a first instant in time and the digital mirror sense signal at a second instant in time, determines whether the difference exceeds a threshold, and indicates failure of the movable MEMS mirror as a function of the difference failing to exceed the threshold.

  • Patent number: 10048317
    Abstract: A chain of flip-flops is tested by passing a reference signal through the chain. The reference signal is generated from a test pattern that is cyclically fed back at the cadence of a clock signal. The reference signal propagates through the chain of flip-flops at the cadence of the clock signal to output a test signal. A comparison is carried out at the cadence of the clock signal of the test signal and the reference signal, where the reference signal is delayed by a delay time taking into account the number of flip-flops in the chain and the length of the test pattern. An output signal is produced, at the cadence of the clock signal, as a result of the comparison.

  • Patent number: 10050672
    Abstract: A method is for processing an analog signal coming from a transmission channel. The analog signal may include a useful signal modulated on a sub-set of carriers. The method may include analog-to-digital converting of the analog signal into a digital signal, and synchronization processing the digital signal. The synchronizing may include determining, in a time domain, a limited number of coefficients of a predictive filter from an autoregressive model of the digital signal, and filtering the digital signal in the time domain by a digital finite impulse response filter with coefficients based upon the limited number of coefficients to provide a filtered digital signal. The method may include detecting of an indication allowing a location in the frame structure to be identified, using the filtered digital signal and a reference signal.
