| description | A MEMS resonant sensor adapted to generate a pulse output signal from a signal of interest, the signal of interest being a signal having a frequency oscillating around a carrier frequency, the MEMS sensor comprising at least one processing channel for processing the signal of interest, each processing channel comprising: a demodulation unit for demodulating the signal of interest in order to form a demodulated signal, the demodulation unit comprising a frequency mixer between the signal of interest and a reference signal, the demodulated signal having a low-frequency component and a high-frequency component; a filtration unit for filtering the demodulated signal in order to form a filtered signal, the filtration unit being adapted to allow through the low-frequency component of the demodulated signal; a comparison unit for comparing the filtered signal with a fixed threshold signal in order to form a comparison signal, the comparison signal comprising rising edges and falling edges; a detection unit for detecting rising edges, each rising edge corresponding to a pulse of the output signal. |
