Claim Text:
1. An electric field sensor, comprising: at least one sensing electrode for detecting an electric field and generating an input signal; a sensor input connected to the at least one sensing electrode for receiving the input signal; an integrated amplifier adapted to generate at least one buffered output signal that replicates the input signal, the integrated amplifier comprising a substrate, a package assembly and a plurality of circuit elements integrated on the substrate and enclosed within the package assembly, each circuit element comprising a plurality of terminals, wherein a first portion of the plurality of terminals is connected to the sensor input; an active shield in electrical communication with an output of the integrated amplifier so that the at least one buffered output signal drives the active shield; and wherein the first portion of the plurality of terminals is shielded from the substrate and the package assembly by a second portion of the plurality of terminals substantially following one of the input signal and the buffered output signal.
