Classification: CPC H | IPC H

Claim 0:
1. An analog-to-digital converter comprising:
an analog amplification unit configured to input an input signal and a reference signal and sequentially output a first output signal based on the input signal, a second output signal obtained by converting the first output signal into a digital value and the reference signal selected according to the digital value of the second output signal; and
a flash conversion unit configured to input the first output signal, output the second output signal, and generate and output an output code based on the second output signal,
wherein the analog amplification unit comprises:
a first input unit configured to output a first intermediate signal obtained by subtracting a value of the reference signal selected by the second output signal from the input signal;
a second input unit configured to output a second intermediate signal obtained by subtracting the value of the reference signal selected by the second output signal from the first output signal; and
an amplification unit configured to output the first output signal obtained by amplifying a difference between the first intermediate signal and the second intermediate signal.
