    摘要： A polar modulator contains a first input for supplying an amplitude modulation word and a second input for supplying a phase modulation word. The first input is connected to a first signal path, and the second input is connected to a second signal path. The polar modulator contains a converter having a first input which is connected to a first signal path and having a second input which is connected to the second signal path. In this case, the converter is configured to output a radio-frequency signal derived from the phase modulation word and the amplitude modulation word. A feedback path has a level detector connected to the converter and has its output side connected to a correction device. The correction device is designed to output a correction word to the first signal path on the basis of a signal which is output by the level detector.

    摘要： A voltage-controlled oscillator circuit compensates for supply voltage fluctuations of the oscillator and thus for frequency fluctuations at the oscillator output. An additional voltage-controlled capacitor is connected in parallel with the voltage-controlled capacitor of the LC resonant circuit. The control terminal of the second voltage-controlled capacitor is coupled to the supply voltage terminal, which feeds the oscillator circuit. The oscillator circuit can be monolithically integrated and can be employed in phase-locked loops, for example.
