WIPO Patent Application WO/2020/130213
Kind Code:
A1
Abstract:
Provided is a bandwidth variable analog-to-digital converter for sensors. A multi-sensor signal processing device according to an embodiment of the present invention comprises: a multiplexer for selecting one of a plurality of sensors; an analog-to-digital converter for converting, to a digital signal, an analog signal output from a sensor selected by the multiplexer; and a controller for controlling sampling frequency of the analog-to-digital converter according to the sensor selected by the multiplexer. Accordingly, it is possible to operate the analog-to-digital converter for a longer period of time during battery operation by reducing unnecessary power consumption.
