Claim 16:
17. The device recited in claim 12, wherein the multiplexer is a first multiplexer, the read amplifier is a first read amplifier, and the digitizer is a first digitizer, and further comprising:
a second multiplexer;
a third nanopore unit, the third nanopore unit comprising a third nanopore, a third sense electrode, a third counter electrode, and a third shield situated between the third sense electrode and the third counter electrode and coupled to the second multiplexer;
a third shield driver coupled to the third shield;
a fourth nanopore unit, the fourth nanopore unit comprising a fourth nanopore, a fourth sense electrode, a fourth counter electrode, and a fourth shield situated between the fourth sense electrode and the fourth counter electrode and coupled to the second multiplexer;
a fourth shield driver coupled to the fourth shield;
a second read amplifier coupled to the second multiplexer; and
a second digitizer coupled to the second read amplifier, and wherein:
the drive circuitry is further coupled to the third nanopore unit and the fourth nanopore unit,
the control logic is further coupled to the second multiplexer and to the second digitizer, and
the control logic is further configured to:
control at least one of the drive circuitry or the second multiplexer to select the third nanopore unit, and
obtain a second digitized signal from the second digitizer, the second digitized signal representing a current through the third nanopore.
