Abstract
An amplifier for an active electrode is described which requires only a two-conductor connecting cable, is current limiting for patient safety, and has essentially unity voltage gain. In addition, the output impedance is lower and the input impedance has more adjustment latitude than is possible with a conventional source follower.
