Measurement method or apparatus for measuring physical phenomena or chemical phenomena

摘要

PROBLEM TO BE SOLVED: To provide a measuring method or apparatus that quantify a physical or chemical phenomenon by converting them into electric charge information and has high measurement accuracy, excellent responsiveness, and high linearity.;SOLUTION: The measuring apparatus has a detecting section comprising an electric charge feeding portion 1 for feeding the electric charge to a sensing portion 3, the sensing portion 3 having potential changed depending on the magnitude of physical or chemical amount, and a floating diffusion 7 for removing the fed electric charge to the sensing portion 3. Between the sensing portion 3 and the floating diffusion 7, there are a sensing electric charge accumulating portion 5 that accumulates the electric charge transmitted from the sensing portion 3 and has a reset gate 8a for releasing a part of the accumulated electric charge, and a weir portion 6 for transmitting the remaining charge to the floating diffusion 7.;COPYRIGHT: (C)2006,JPO&NCIPI
