Abstract
Circuitry for measuring a characteristic of an electrochemical cell, the electrochemical cell comprising at least one working electrode and a counter electrode, the circuitry comprising: driver circuitry configured to apply a working bias voltage to the at least one working electrode and a counter bias voltage at the counter electrode to produce a first voltage bias between the at least one working electrode and the counter electrode; control circuitry configured to adjust the first voltage bias over a first bias range by varying the working bias voltage and the counter bias voltage.

Circuitry for measuring a characteristic of an electrochemical cell, the electrochemical cell comprising at least first, second, and third electrodes, the circuitry comprising:
- driver circuitry configured to:
- apply a first bias voltage to the first electrode and a second bias voltage at the second electrode to produce a first voltage bias between the first electrode and the second electrode;
- apply a third bias voltage to the third electrode to produce a second voltage bias between the second electrode and the third electrode;
- control circuitry configured to adjust the first voltage bias over a first bias range by varying the first voltage and the second voltage.
