PROBLEM TO BE SOLVED: To provide a comparison circuit capable of power-saving high speed operation which permits an offset to be adjusted to zero or a threshold to be set to an arbitrary level.SOLUTION: The comparison circuit includes: a differential amplification circuit operatively switched in response to a clock signal CLK to output a first intermediate output DP and a second intermediate output DN corresponding to a first input signal VIP and a second input signal VIN; and a differential latch circuit operatively switched in response to the clock signal to make a state change depending on the first intermediate output and the second intermediate output, and having controllable sensitivity of the state change to the first intermediate output and the second intermediate output. |
