Abstract
Systems and methods for converting a capacitance signal into a band-limited voltage signal for improved signal processing are disclosed herein. Such systems can include a capacitance-to-voltage converter configured to convert a capacitive signal from a capacitive device that operates at a mechanical frequency into a raw voltage signal, a clock generator configured to convert the mechanical frequency into one or more clock signals, and a filter component configured to apply a band-pass filter response to the raw voltage signal to convert the raw voltage signal into a band-limited voltage signal. The clock generator can be configured to apply the one or more clock signals to the filter component to drive a first pole and a second pole of the band-pass filter response to track the mechanical frequency of the capacitive device such that the geometric mean of the first pole and the second pole is substantially equal to the mechanical frequency.
