  • Publication number: 20180321308
    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.

  • Publication number: 20180321727
    Abstract: An integrated processing unit is supplied by a power supply voltage present at the terminals of a capacitor configured to supply a maximum permissible voltage drop. A periodic pulse signal is generated having a period that is less than or equal to a current period determined from the maximum permissible voltage drop and a current consumption of the processing unit. The power supply voltage is compared with a threshold voltage at the pulse rate of the periodic pulse signal. A control signal generated from that comparison is delivered to the processing unit and has a first value when the power supply voltage is greater than or equal to the threshold voltage and a second value when the power supply voltage is less than the threshold voltage.

  • Patent number: 10122277
    Abstract: A method of controlling a switching regulator includes detecting current-limit events indicating a maximum current threshold has been exceeded. A compensation voltage is adjusted in response to the detected current-limit events, where the compensation voltage defines a duty cycle of the switching regulator. A time is detected for which no current-limit events have been detected and the value of the compensation voltage is adjusted to increase the duty cycle of the switching regulator in response to the detected time exceeding a time step threshold.

  • Patent number: 10122557
    Abstract: A method of wireless communication includes transmitting frames from a transponder to a reader and synchronizing between a reader carrier frequency and an active load modulation (ALM) carrier frequency within each transmitted frame. Each transmitted frame includes ALM carrier bursts generated from subcarrier modulation by binary phase shift keying (BPSK) data encoding and producing signal oscillations at a transponder antenna after each ALM carrier burst generation, The synchronizing occurs at each phase change of the data encoding when no burst is generated during a half period of the subcarrier preceding the phase change and a half period of the subcarrier following this phase change. The transponder antenna has a moderate quality factor sufficient to naturally damp the signal oscillations so that the synchronizing is performed without performing any controlled signal oscillations damping.
