CHARGE SAMPLING FILTER CIRCUIT AND CHARGE SAMPLING METHOD |
摘要 |
(Problem) To provide a charge sampling filter circuit and a charge sampling method. (Means for Resolution) A charge sampling filter circuit includes a first capacitor that samples an input signal, and in which at least a portion of electric charge stored in the first capacitor by sampling is output to a second capacitor that is connectable with the first capacitor. The charge sampling filter circuit is characterized by including a switching portion that switches a circuit mode including a sampling mode that causes the first capacitor to sample the input signal, and an output mode that causes the first capacitor and the second capacitor to be connected. A capacitance value of the first capacitor in the output mode is set to be lower than the capacitance value in the sampling mode.
