DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of simplifying a circuit configuration in order to miniaturize a detector which detects variations in the potential of an electrode.SOLUTION: A detector for detecting variations in a potential of an electrode is disclosed. The detector includes a detection circuit having: a first switching element for switching on and off a current output; a capacitor provided between the electrode and a gate terminal of the first switching element; and a second switching element for switching conduction and non-conduction between the gate terminal of the first switching element and a reset signal line.SELECTED DRAWING: Figure 8
