SAMPLING CIRCUIT, SAMPLING METHOD, AND PHOTO DETECTING APPARATUS

摘要

PURPOSE: A sampling circuit, a sampling method, and an optical sensing apparatus are provided to minimize interference due to offset in case a signal of a unit cell is weak. CONSTITUTION: An offset compensation reference signal generating unit(30a) inputs a first signal including offset information. The offset compensation reference signal generating unit compensates for the offset information of a reference signal. The offset compensation reference signal generating unit generates the compensated reference signal. A comparing unit(21) inputs a second signal including data information.
