摘要：According to an embodiment, a system for amplifying a signal provided by acapacitive signal source includes a first stage and a second stage. The first stage has avoltage follower device including an input terminal configured to be coupled to a first

terminal of the capacitive signal source, and a first capacitor having a first end coupled toan output terminal of the voltage follower device, and a second end configured to becoupled to a second terminal of the capacitive signal source. The second stage includes adifferential amplifier capacitively coupled to the output terminal of the voltage followerdevice.
