摘要： A bulk acoustic wave resonator has an adjustable resonance frequency. A piezoelectric element is provided having first and second electrodes. A switching element is provided in the form of a MEMS structure which is deformable between a first and second position. The switching element forms an additional electrode that is selectively disposed on top of, and in contact with, one of the first and second electrodes. This causes a total thickness of the electrode of the resonator to be changed resulting in a modification of the resonance frequency of the resonator.

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.
