The detector and the method of detection which possess low sensitivity vis-a-vis three-dimensional fluctuation and temperature fluctuation

摘要

The detection amplifier is disclosed. One execution configuration is the detector (106) which possesses the detection transistor (287) which is jointed to the detection device (104) and that detection device. The 1st switch (288) which is jointed to the detection transistor and the detection device, makes the detection device the 1st voltage charge which is function of threshold voltage of the detection transistor. At least one 2nd switch (282, 293, 291 and 289), is jointed to the detection device and the target component (10). The 2nd switch, making the detection device the target component joint, as alteration the 1st voltage of the detection device, makes the detection device and the target component no connection in the detection phase where the 1st voltage alteration is impressed in the detection transistor. State of the target component, although aforementioned the aforementioned 1st voltage alteration is impressed in the aforementioned detection transistor, responding, whether or not the aforementioned detection transistor turns turns in the basis is decided of.
