Abstract
A distance detection sensor includes a current-to-voltage converter configured to convert a current corresponding to a detection signal reflected from a target to a voltage, an amplifier configured to amplify the converted voltage, a comparator configured to compare an output value of the amplifier with a reference value to generate a receive pulse, a reference value selector configured to select any one of a plurality of reference values as the reference value, and a time-to-digital converter configured to calculate time-of-light (TOF) time in response to the receive pulse output from the comparator. The reference value selector continuously changes different reference values respectively corresponding continuous receive pulses.
