BUFFERED BODY RETURN RECEIVER
First Claim
1. A buffered body return receiver, comprising:
- an amplifier connected to a power supply electrically independent from a signal source;
a first electrode connected to a non-inverting input of the amplifier; and
a second electrode connected to an inverting input of the amplifier and an output of the amplifier as a driven node.

Abstract
Buffered body return receiver configurations are described. An amplifier for a receiver can be connected to two electrodes such that one of the two electrodes is connected to a non-inverting input of the amplifier and a second of the two electrodes is a driven node by being connected to both the inverting input of the amplifier and the output of the amplifier. The amplifier may be connected as a fully differential amplifier, a single-ended differential amplifier, a buffer, or an amplifier with a gain greater than 1, while still enabling improved channel gains with reduced power consumption at the transmitter from the signal source. The buffered body return receiver is suitable for scenarios in which a signal source is electrically independent of the power supply of the receiver'"'"'s amplifier.
