CPC G01N 27/028 (2013.01) [G01N 27/3273 (2013.01); G01N 27/416 (2013.01); G01N 27/49 (2013.01)] | 18 Claims |
1. A system comprising:
a plurality of electrodes configured to electrically couple to an electrochemical system; and
a feedback mechanism including a voltage buffer and a cascaded amplifier pair, wherein
the voltage buffer is configured to detect a potential associated with the electrochemical system via
a first electrode of the plurality of electrodes, and generate a first signal indicative of the detected potential,
wherein the cascaded amplifier pair is configured to receive the first signal and a set potential value, and provide a feedback signal to the electrochemical system via a second electrode of the plurality of electrodes, wherein the feedback signal is configured to provide an excitation control of the electrochemical system at a third electrode of the plurality of electrodes.
