Abstract
Disclosed herein is a method of operating a single slope analog-to-digital converter (ADC), which includes receiving an input signal from a sensor or a ramp signal from a ramp generator according to a state of a switch and sampling the received input or ramp signal, comparing, by a comparator, whether the sampled ramp signal is present in a predetermined input range in a state in which the ramp generator maintains an off state and outputting the comparison result, generating, by a logic part, a flag signal indicating a high or low according to the comparison result by the comparator and providing the flag signal to the ramp generator, and sampling, by the ramp generator, a reference voltage of the comparator according to the flag signal based on an off or on state.
