- An apparatus for cancellation of a transient voltage spike, includes: a first photodiode for detecting a photon in an optical signal input from an outside, a second photodiode for detecting the photon in the optical signal input from the outside, and a differential amplifier for canceling the same signal component in a first output signal of the first photodiode and a second output signal output from the second photodiode, and to amplify a voltage difference between the first output signal and the second output signal. The transient voltage spike cancellation apparatus cancel a transient voltage spike occurring in an avalanche photodiode operating in a gated Geiger mode, using the differential amplifier.
