Abstract
Official abstract text for this publication.
According to an embodiment, an analog-to-digital converter includes a first AD (analog-to-digital) conversion circuit and a second AD conversion circuit. The first AD conversion circuit performs AD conversion of a first input signal to generate an upper-bit digital signal. The second AD conversion circuit performs AD conversion of a sampled signal to generate a lower-bit digital signal. The sampled signal is obtained by sampling a residual signal corresponding to a residue of the AD conversion in the first AD conversion circuit. A period during which the second AD conversion circuit performs AD conversion of the sampled signal overlaps a period during which a second input signal subsequent to the first input signal is settled.
First claim
Opening claim text (preview).
What is claimed is: 1. An analog-to-digital converter comprising: a first analog-to-digital conversion circuit which performs analog-to-digital conversion of a first input signal to generate an upper-bit digital signal; and a second analog-to-digital conversion circuit which performs analog-to-digital conversion of a sampled signal to generate a lower-bit digital signal, the sampled signal being obtained by sampling a residual signal corresponding to a residue of the analog-to-d…
