Patent number: 9396370Abstract: A carrier compensation reader compensates a carrier signal. The carrier compensation reader transmits, via an antenna, a first carrier signal and obtains a second carrier signal based on the first carrier signal. The carrier compensation reader configures a compensation circuit to receive a receiver output signal based on the second carrier signal and generate a compensation signal based on the receiver output signal to compensate the second carrier signal. The carrier compensation reader obtains a carrier compensation signal summing the second carrier signal and the compensation signal.Type: GrantFiled: April 25, 2013Date of Patent: July 19, 2016Assignee: Atmel CorporationInventors: Marco Schwarzmueller, Ulrich Grosskinsky, Wolfgang Schneider

Patent number: 8767877Abstract: A method for controlling a receiver circuit and circuit with a receiver circuit and with a control circuit is provided, whereby a received signal is demodulated and filtered. An amplitude value of the demodulated and filtered signal is compared with thresholds of a window comparator. A zero crossing of the demodulated and filtered signal is compared with time thresholds of a time window by a comparison unit. A first output value of the window comparator and a second output value of the comparison unit are logically combined, and wherein, via the logical combination, the receiver circuit is turned off if, within a period of time, the amplitude value is determined to be outside a window formed by the thresholds of the window comparator, or a zero crossing is determined to be outside the time window.Type: GrantFiled: March 9, 2010Date of Patent: July 1, 2014Assignee: Atmel CorporationInventors: Ulrich Grosskinsky, Werner Blatz

Patent number: 8155240Abstract: A receiver circuit, application of a first proportional element and a second proportional element of a digital PLL structure, and method for receiving a frequency-shift keyed signal are provided. A phase signal is calculated from an in-phase signal and a quadrature signal. A feedback signal is subtracted from the phase signal to form a difference signal. An output signal is determined from the difference signal by a nonlinear transfer function. The output signal is evaluated with an evaluation circuit. A first signal and a second signal are added to form a summation signal. The first signal is produced by multiplication of the output signal or the difference signal by a first proportionality factor. The second signal is produced by multiplication of the output signal or the first signal or the difference signal by a second proportionality factor, followed by integration, and the feedback signal is produced by integration of the summation signal.Type: GrantFiled: November 12, 2008Date of Patent: April 10, 2012Assignee: Atmel CorporationInventor: Ulrich Grosskinsky
