The invention relates to a frequency generator assembly, including at least one oscillator and an electronic signal processing device, which is designed in such a way that the electronic signal processing device provides an electric clock signal (f) having a defined frequency as an output signal of the frequency generator assembly, wherein the defined frequency depends on the vibration frequency of the oscillator, wherein the oscillator includes at least one micromechanical seismic mass which is vibrationally excited by at least one driving device, whereupon the electronic signal processing device generates and provides the electric clock signal (f) according to the vibration frequency of the at least one seismic mass.. .

Digital class-d amplifier and digital signal processing method
A digital class d amplifier (10) is disclosed, comprising a pulse width modulator (pw mod) comprising: a digital loop filter (loop f) adapted to receive an input signal (x[n]) and a feedback signal (fb[n]), the digital loop filter (loop_f) being adapted to process at a clock frequency (f_s) said input and feedback signals for providing as output a filtered digital signal (w[n]); a pwm conversion module (pw_cm) having an input (24) for receiving the filtered digital signal (w[n]) and having a first output (25) connected to the digital loop filter (loop f), the pwm conversion module being adapted for processing the filtered digital signal (w[n]) and providing at said first output (25) the feedback signal (fb[n]). The pwm conversion module (pw_cm) comprises: a first comparator (cmp_n) adapted to compare the filtered digital signal (w[n]) with a first reference triangular waveform (vtn[n]) for providing as output a first pwm signal (yn[n]), the first reference triangular waveform having a frequency (f_osc) much lower than said clock frequency (f.s); a second comparator (cmp_p) adapted to compare the filtered digital signal (w[n]) with a second reference triangular waveform (vtp[n]) for providing as output a second pwm signal (yp[n]), the second reference triangular waveform (vtp[n]) being the inverse of the first triangular waveform (vtn[n]), said first (yn[n]) and second (yp[n]) pwm signals representing a differential output pulse width modulated signal (yn[n],yp[n])..
