Analog-digital converter and image sensor

An analog-digital converter performs AD conversion of an upper m bits by sequential comparison, and performs AD conversion of a lower n bits by integration. This increases accuracy, reduces power consumption during operation, reduces variation between analog signals and digital signals, and reduces the required layout area by decreasing the number of capacitor elements needed. Also, the AD conversion of the n bits by integration is performed by ramp voltage quantized with a margin of k bits of the lower n bits. As such, preferable AD conversion characteristics can be obtained when offset or the like is produced in a DA conversion circuit for generating ramp voltage.
