Open-Loop Switched-Capacitor Integrator for Low Voltage Applications [PDF]
Electronics, 2020 An architecture of a switched-capacitor integrator that includes a charge buffer operating in an open-loop is hereby proposed. As for the switched-capacitor filters, the gain of the proposed integrator, which is given by the input/output capacitor ratio, ensures desensitization to process, voltage, and temperature variations.

Novel switched-capacitor generalised integrator
Electronics Letters, 1985 A novel circuit arrangement is proposed for a generalised integrator using the switched-capacitor (SC) technique. This generalised integrator (which integrates with respect to a dependent variable) can easily be constructed in IC form using MOS technology. It possesses some attractive features, for instance simplicity and low cost.

A Low-Power Delta-Sigma Capacitance-to-Digital Converter for Capacitive Sensors
IEEE Access, 2019 This paper proposes a low-power delta-sigma capacitance-to-digital converter (CDC) for a capacitive sensor. The input of the capacitive sensor employs a zoomed-in technique with the offset capacitor to extend the input capacitance range. The proposed CDC
