In accordance with an embodiment, a system for amplifying a signal provided by a capacitive signal source includes a first voltage follower device, a second voltage follower device, and a first capacitor. The first voltage follower device includes an input terminal configured to be coupled to a first terminal of the capacitive signal source, and the second voltage follower device includes an input terminal coupled to a first output terminal of the first voltage follower device and an output terminal coupled to a second output terminal of the first voltage follower device. Furthermore, a first capacitor includes a first end coupled to the first output terminal of the first voltage follower device and a second end configured to be coupled to a second terminal of the capacitive signal source. |
