Title:
DATA ACQUISITION CIRCUIT AND BIOSENSOR
Document Type and Number:
WIPO Patent Application WO/2024/043266
Kind Code:
A1
Abstract:
A data acquisition circuit according to the present invention has a plurality of signal processing units which each have a first analog chopper circuit, an amplifier, a second analog chopper circuit, and an analog filter that are connected in series. In a first mode, the data acquisition circuit converts analog signals from the analog filters into digital signals in series, and filters the digital signals after conversion in parallel. In a second mode, the data acquisition circuit converts analog signals from the amplifiers into digital signals in series, thereafter outputs the digital signals to a digital chopper circuit, and filters the digital signals from the digital chopper circuit after conversion in parallel. This makes it possible to appropriately acquire biological information in a plurality of frequency bands.
