Abstract
A receiving circuit includes a clock generation circuit that generates a clock signal, an integration filter that stores a signal potential of an input signal and generates a first storage potential in a period in which the clock signal indicates one logic, a first analog-to-digital circuit that converts the first storage potential into a first digital value, and a data determination circuit that determines a logic of the input signal on a basis of the first digital value.
Claims8
A receiving circuit comprising:
- a clock generation circuit that generates a clock signal;
- an integration filter that generates a first storage potential based on a potential of an input signal in a period in which the clock signal indicates one logic;
- a first analog-to-digital circuit that converts the first storage potential into a first digital value;
- and
- a data determination circuit that determines a logic of the input signal on a basis of the first digital value.

A receiving circuit comprising:
- a clock generation circuit that generates four clock signals having respective pulse periods of 90 degrees, the pulse periods being different from each other by 90 degrees and one cycle being associated with 360 degrees;
- an integration filter that generates a first storage potential, a second storage potential, a third storage potential, and a fourth storage potential based on potentials of an input signal in the corresponding pulse periods of the clock signals;
- an arithmetic-operation circuit that generates an arithmetic-operation potential by performing an arithmetic operation on two selected ones of the first storage potential, the second storage potential, the third storage potential, and the fourth storage potential;
- an analog-to-digital circuit that converts the arithmetic-operation potential into a digital value;
- and
- a data determination circuit that determines a logic of the input signal on a basis of the digital value.
