摘要： The frequency synthesizer includes a phase-locked loop (PLL). The PLL includes an oscillator controlled to deliver an output signal at a predefined output frequency, a variable frequency divider to convert the output signal into a divided-frequency signal, a phase comparator to produce a signal measuring a phase difference between the divided-frequency signal and a reference signal at a reference frequency, and a loop filter to control the oscillator on the basis of the measurement signal. To increase the speed of convergence of the synthesizer if the set point is changed, the loop filter of the PLL is a fractional, i.e. non-integer, order low-pass filter.

摘要： A phase locked loop includes a controlled oscillator for delivering an output signal at a determined output frequency, and a variable frequency divider for converting the output signal into a signal at divided frequency. The PLL is termed composite in that it includes at least one first loop having a loop filter for generating a first control signal for the oscillator on the basis of the signal at divided frequency, and a second loop having a loop filter, different from the loop filter of the first loop, for generating, on the basis of the signal at divided frequency, a second signal for additional control of the oscillator. The loop filter of the first loop and the loop filter of the second loop have different respective cutoff frequencies. The passband of the first loop, can be adapted to ensure the convergence and the stability of the PLL, while the second loop can afford extra passband increasing the speed of adaptation of the PLL in case of modification of the value of a preset for the output frequency.
摘要翻译：锁相环包括用于以确定的输出频率输出输出信号的受控振荡器和用于将输出信号转换为分频的信号的可变分频器。 PLL被称为复合，因为它包括至少一个具有环路滤波器的第一环路，该环路滤波器基于分频频率的信号产生用于振荡器的第一控制信号，以及具有不同于环路的环路滤波器的第二环路滤波器，用于基于分频后的信号产生用于对振荡器进行附加控制的第二信号。第一回路的环路滤波器和第二回路的环路滤波器具有不同的各自的截止频率。第一个环路的通带可以适应于确保PLL的收敛和稳定性，而第二个环路可以提供额外的通带，在修改输出预置值的情况下可以提高PLL的自适应速度频率。

摘要： A method is for reducing a DC component of an input signal transposed into baseband and being generated by a first frequency transposition stage starting from an initial signal and from a transposition signal. The method includes amplifying the transposed input signal in a first amplifier. The first amplifier receives at a DC offset compensation input, a compensation signal extracted from an output signal of a second amplifier subjected to a compensation of a offset DC voltage of the second amplifier. The method also included alternating between receiving at an input of the second amplifier, a first auxiliary signal from an auto-transposition of a transposition signal in a second frequency transposition stage and a second auxiliary signal from a transposition of the initial signal in the second frequency transposition stage with the transposition signal.

摘要： A distributed oscillator includes an odd number of serially connected amplifying elements. An output of a last amplifying element is looped back to an input of a first amplifying element via a first transmission line. The oscillator oscillates at a first frequency f1. The oscillator further includes circuitry for injecting a control signal onto the input of the first amplifying element. The control signal has a second frequency f2 which is a sub-multiple of the first frequency f1.
