Abstract
An interpolation circuit includes: a plurality of holding circuits configured to each hold a corresponding input data input chronologically; and a generating circuit configured to generate interpolation data by giving weights, based on an interpolation code, to input data that are chronologically adjacent to each other and are held by the plurality of holding circuits and combining the weighted data together.
Claims16
An interpolation circuit comprising:
- a plurality of holding circuits each configured to hold, using respective capacitors, corresponding input data that are inputted chronologically;
- and
- a generating circuit configured to generate interpolation data by performing a weighting operation on at least two pieces of the input data, which are chronologically adjacent to each other and are outputted by the plurality of holding circuits, based on an interpolation code that is used for generating interpolation data from the at least two pieces of the input data and combining weighted data of the at least two pieces of the input data.
A receiving circuit comprising:
- an interpolation circuit configured to generate interpolation data;
- and
- a detection circuit configured to detect a phase of the interpolation data, and generate an interpolation code,
- wherein the interpolation circuit is configured to include:
- a plurality of holding circuits each configured to hold, using respective capacitors, corresponding input data that are inputted chronologically;
- and
- a generating circuit configured to generate the interpolation data by performing a weighting operation on at least two pieces of the input data, which are chronologically adjacent to each other and are outputted by the plurality of holding circuits, based on the interpolation code that is used for generating the interpolation data from the at least two pieces of the input data and combining the weighted data of the at least two pieces of the input data.
