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.
