  • Patent number: 9515705
    Abstract: A near field communications (NFC) device is disclosed that detects an envelope of a radio frequency (RF) signal. The NFC device includes a peak detector that determines the envelope of the RF signal. The peak detector compares a first differential signal voltage to a second differential signal voltage. The peak detector delays a rising edge of a first differential signal and provides the first differential signal voltage to the peak detector output when the first differential signal voltage is greater than the second differential signal voltage. The peak detector delays a falling edge of a second differential signal and provides the second differential signal voltage to the peak detector output when the second differential signal voltage is greater than the first differential signal voltage.

  • Patent number: 9031505
    Abstract: A communications device is disclosed that includes a united integrated circuit card (UICC) that provides a single wire protocol (SWP) current signal to a near field communications (NFC) device. The SWP current signal is filtered by a filter to remove noise from the SWP current signal. The filter is precharged by a reference voltage when the SWP current signal is in a low state and then filters the SWP current signal when the SWP current signal is in a high state. A switching network provides the filter with the reference voltage to precharge when the SWP is current signal is in the low state and then provides the filter with the SWP current signal to filter when the SWP current signal is in the high state.

  • Patent number: 6054892
    Abstract: A timing circuit, for use in an integrated circuit, generates relatively long time periods. The electrical properties (for example the resistance) of a pair of matched components are measured while heat is supplied to one of the components. When the values of the thermally dependent properties of the components differ by a certain amount, the timed period is over. The pair of matched components are located within thermally insulating structures within the IC.
