摘要： An integrator having a first circuit including an integrating capacitor and a feedback resistor, both being connected in parallel to each other in a negative feedback loop of the first circuit, and a second circuit, connected to an output side of the first circuit, for compensating for a leak by the feedback resistor. The first circuit operates as an integrator in high frequencies, and as a current-voltage converter in low frequencies. Further, the second circuit compensates for the leak by the feedback resistor, thereby to produce a value indicative of the result of integrating an input current.

摘要： A charged particle generator includes a first electrode, a second electrode, and an insulating material that is provided between the first electrode and the second electrode. The second electrode has an opening that opens in a first direction in which the first electrode, the insulating material, and the second electrode are arranged. The insulating material has a region limiting space. The region limiting space corresponds to the opening. The region limiting space is continuous with the opening. The region limiting space is a space that opens in a direction in which the region limiting space is oriented toward the opening and that is limited in a second direction perpendicular to the first direction. The first electrode has an anisotropic resistance portion in which a resistance component in the first direction is smaller than a resistance component in the second direction.

摘要： In an amplifier circuit with an offset cancel circuit, on the output side of a non-inversion amplifier circuit, there is connected a sampling circuit including an analog switch composed of two MOS transistors. A source-follower circuit is connected to the output terminal of the sampling circuit. The output voltage of the source-follower circuit is applied to a series resistance formed between two resistances. A connecting point between the resistances is connected to the inversion input terminal of an operational amplifier forming the non-inversion amplifier circuit and thus the divisional component of the output signal of the source-follower circuit is applied to the inversion input terminal of the operational amplifier.
