Abstract:
A biasing circuit for a capacitive sensor includes a capacitive sensor element configured to produce a sensor voltage at a sense node, and a preamplifier connected to the sense node and configured to amplify the sensor voltage. The biasing circuit has an auxiliary amplifier connected between an output of the preamplifier and the sense node and configured to set a DC component of an input voltage for the preamplifier to a ratiometric DC bias voltage.

Claim (Index 8):
A biasing circuit for a capacitive sensor, the biasing circuit comprising:\n a capacitive sensor element configured to produce a sensor voltage at a sense node; a preamplifier connected to the sense node and configured to amplify the sensor voltage; a feedback loop that branches off from an output of the preamplifier to a supply line between the sense node and an input of the preamplifier, the feedback loop including:\n an auxiliary amplifier configured to generate a ratiometric DC bias voltage, the auxiliary amplifier having a first input and a second input, the first input being connected to the output of the preamplifer, the second input receiving a ratiometric reference voltage; and \n a high impedance diode network that receives the ratiometric DC bias voltage and sets an input DC bias voltage level for the preamplifier based on the ratiometric DC bias voltage.
