PIPELINE TYPE ANALOG-TO-DIGITAL CONVERTER AND GAIN ERROR CORRECTION METHOD

摘要

PROBLEM TO BE SOLVED: To reduce at least one of an ADC area and power consumption.;SOLUTION: In a stage 10 constituting a pipeline type analog-to-digital converter, capacitors 12, 13, 14, and 15 charge electric charges used for analog-to-digital conversion when a first voltage V1 is applied. A switch 21 is connected to the capacitor 15 and switches voltage applied to the capacitor 15 to a second voltage V2 different from the first voltage V1 in order to correct a gain error caused by the analog-to-digital conversion.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
