Title:
SWITCHED-CAPACITOR AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2020/184075
Kind Code:
A1
Abstract:
This switched-capacitor amplifier comprises a sampling capacitor (Cs), a first switch (S1), a differential amplifier (2), a reference power source (3), a second switch (S2), a third switch (S3), and a control unit (4) that performs ON and OFF control of the first through third switches. The second switch has a serial circuit comprising first and second MOS transistors (S2A, S2B), and a potential-holding capacitor (C1) connected between a ground and a node (N1) that is a shared connection point of the first and second MOS transistors. The back gate of the first MOS transistor is connected to the node.
