Low-Noise Sensor Interfaces

Abstract - Applications, such as autonomous driving, rely on the perception of the environment around us based on extensive sensing. While most signals in the nature are not changing quickly and can be captured with relatively low-bandwidth sensors, most require low-noise sensors. This tutorial goes over the main sources of noise with a focus on capacitive and image sensors. Advanced noise-reduction circuit techniques, such as chopping, correlated-double sampling, and Boxcar sampling, are explained.
