A method for reducing the adverse effects of stray-capacitance on capacitive sensor circuits [PDF]
Review of Scientific Instruments, 2019 We examine the increase in voltage noise in capacitive sensor circuits due to the stray-capacitance introduced by connecting cables. We have measured and modelled the voltage noise of various standard circuits, and we compare their performance against a benchmark without stray-capacitance that is optimised to have a high signal-to-noise ratio for our ...
