Abstract:
This application relates to methods and apparatus for operating MEMS sensors, in particular MEMS capacitive sensors (C MEMS ) such as a microphones. An amplifier apparatus ( 300 ) is arranged to amplify an input signal (V INP ) received at a sense node ( 104 ) from the MEMS capacitive sensor. An antiphase signal generator ( 201; 304 ) generates a second signal (V INN ) which is in antiphase with the input signal (V INP ) and an amplifier arrangement ( 105; 305 ) is configured to receive the input signal (V INP ) at a first input and the second signal (V INN ) at a second input and to output corresponding amplified first and second output signals. This converts a single ended input signal effectively into a differential input signal.

Claim (Index 7):
An amplifier apparatus as claimed in  claim 6  comprising first and second resistances connected in series between a first output node driven with the first output signal and a second output node driven with the second output signal, wherein the common-mode signal is derived from the midpoint of the first and second resistances.
