Abstract
Facilitating an enhanced linearity and acoustic overload point of a sensor is presented herein. A system can comprise a first conductive component that is biased at a first direct current (DC) voltage; a second conductive component that is biased at a second DC voltage that is opposite in polarity to the first DC voltage; a third conductive component that is capacitively coupled to the first conductive component and the second conductive component; and a feedback component that generates a non-inverted output signal, comprising a sum of buffered signals generated via capacitive coupling between the third conductive component and the first and second conductive components, generates an inverted output signal comprising an amplified inversion of the non-inverted output signal, and applies the inverted output signal to the third conductive component.
