摘要： A digital phase locked loop includes a digital phase detector, a downstream digital filter and an oscillator. In addition, a frequency divider resides in a feedback path and has an actuating input for setting a divider ratio, the input of which is connected to the oscillator and the phase detector. The phase locked loop comprises a sigma-delta modulator having a data input for supplying a data word and having an actuating output for supplying a frequency setting word to the actuating input of the frequency divider. The data word is configured such that the sigma-delta modulator generates jitter in the frequency setting word, with the result that the signal which is applied to the feedback input of the phase detector is not constant over a relatively long period of time.

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 phase locked loop is disclosed and includes a frequency divider circuit with a settable division ratio in a feedback path. The division ratio is produced using a control circuit which, besides an input for supplying the integer and fractional components for the frequency division ratio which is to be set, includes an input for supplying a phase correction signal. To produce the phase correction signal, the phase locked loop further includes a phase correction apparatus. The phase correction signal preferably contains a signal component with an exponential profile, and is supplied to the control circuit for producing a frequency division ratio for the frequency divider circuit such that it compensates for a phase drift in the output signal from the voltage controlled oscillator in the phase locked loop.

摘要： A two-point modulator arrangement is specified, said arrangement being developed with respect to conventional two-point modulators to the effect that the high-pass coupling-in point of the modulator that comprises a phase locked loop is formed by an expanded loop filter. In accordance with the present principle, the expanded loop filter comprises a coupling-in element, at which the modulation signal is combined with the output signal of a phase comparator. A voltage-controlled oscillator having only one tuning input can thus advantageously be used.

摘要： A signal processing device is provided that includes a modulation unit that produces an amplitude element as well as a phase element from components that are applied thereto. A correction device is also provided, in which at least one of the components is supplied and is compared with an ideal nominal value. This is used to produce a correction factor, which is multiplied by the component which has been compared with the nominal value. The correction factor determined is used to correct any offset or distortion of the components produced by analog circuits.

摘要： A phase locked loop PLL having a forward path and a feedback path is disclosed. A phase detector drives an oscillator in the forward path of the phase locked loop. The feedback path includes a frequency divider that connects the oscillator output to the phase detector. The phase locked loop further includes an integrator-free loop filter configured to control the oscillator. The integrator-free loop filter enables a reduction in the required PLL bandwidth without reducing the signal quality when the PLL is used as a modulator.

摘要： The invention includes a phase locked loop which has a voltage-controlled oscillator, a phase comparator and a charge pump. The charge pump is coupled to a setting input of the voltage-controlled oscillator via a loop filter. A feedback input of the phase comparator is connected to the output of the voltage-controlled oscillator via a frequency divider, and the phase comparator is designed to output an actuating signal to the charge pump. The loop filter has a first charge store and at least one tunable element that alters a filter characteristic of the loop filter. In addition, there is a trimming circuit which is coupled to the at least one further element in order to alter the filter characteristic of the loop filter and which is designed to compare a time period for a charging operation in a loop filter with a reference time period.
