CONVERSION APPARATUS, IMAGING APPARATUS, ELECTRONIC APPARATUS, AND CONVERSION METHOD |
摘要 |
The present technology relates to a conversion apparatus, an imaging apparatus, an electronic apparatus, and a conversion method that are capable of reducing the scale of a circuit.;The conversion apparatus includes: a comparison unit that compares an input voltage of an input signal and a ramp voltage of a ramp signal that varies with time; and a storage unit that holds a code value when a comparison result from the comparison unit is inverted, the holding of the code value by the storage unit being repeated a plurality of times, to generate a digital signal having a predetermined bit number. The predetermined bit number is divided into high-order bits and low-order bits, the low-order bits are acquired earlier than the high-order bits, and the acquired low-order bits and the high-order bits are combined with each other, to generate the digital signal having the predetermined bit number. The present technology can be applied to a portion of an image sensor, in which AD conversion is performed. |

1. A conversion apparatus, comprising:
a comparison unit that compares an input voltage of an input signal and a ramp voltage of a ramp signal that varies with time; and a storage unit that holds a code value when a comparison result from the comparison unit is inverted, the holding of the code value by the storage unit being repeated a plurality of times, to generate a digital signal having a predetermined bit number. |
