Title:
CURRENT SENSOR FOR BIOMEDICAL MEASUREMENTS
Document Type and Number:
WIPO Patent Application WO/2019/109363
Kind Code:
A1
Abstract:
A current sensor for biomedical measurements includes: a first amplifier; a first capacitor; a second capacitor; a first switch connected in parallel with the first capacitor; a second switch connected in parallel with the second capacitor; a second amplifier; a third capacitor; a resistor; and a switched capacitor network. The first capacitor and the second capacitor are connected in series and across a first input and output of the first amplifier. The third capacitor and the resistor are respectively connected across a first input and output of the second amplifier. The switched capacitor network is connected between the output of the first amplifier and the first input of the second amplifier.
