摘要： A signal generator for a transmitter or a receiver for transmitting or receiving RF-signals according to a given communication protocol includes an oscillator and a mismatch compensator. The oscillator is configured to provide a signal generator output signal having a signal generator output frequency and comprises a fine tuning circuit for providing a fine adjustment of the signal generator output frequency based on a fine tuning signal and a coarse tuning circuit for providing a course adjustment of the signal generator output frequency based on a coarse tuning signal. The mismatch compensator is configured to receive the signal generator output signal and compensate a frequency mismatch between a desired signal generator output frequency and the signal generator output frequency generated by the oscillator by providing the fine tuning signal for changing the state of the fine tuning circuit of the oscillator and by providing the coarse tuning signal for changing a state of the coarse tuning circuit of the oscillator. The mismatch compensator provides the coarse tuning signal during a guard period defined in the given communication protocol, during which no RF-signals are transmitted by the transmitter or no RF-signals are to be received by the receiver, such that the state of the coarse tuning circuit is changed within the guard period.

摘要： In a receiver circuit for demodulating a high-frequency signal, a limiting amplifier stage with a downstream sigma-delta converter is connected in series with a mixer stage that transforms a high-frequency signal that is supplied at its input into an intermediate-frequency signal. The intermediate-frequency signal at the output of the limiting amplifier stage is value-discrete and time-continuous. The described receiver architecture has a high sensitivity, is substantially independent of production tolerances, and occupies a small area; therefore, it is particularly suitable for mobile radio applications.
