Abstract

An apparatus for bootstrapping an amplifier of a capacitive displacement transducer. The apparatus replaces a transformer with two capacitors and two resistors configured to provide biased supply voltages to the positive and negative power supply connections of an amplifier configured as a high impedance unity gain buffer in the transducer. The replacement of the transformer with a pair of standard capacitors and resistors provides for similar performance at a reduced size and cost.
