The present invention provides a time-of-flight sensor () including at least one time-of-flight pixel () for demodulating a received modulated light beam (Sp), wherein the time-of-flight pixel () comprises at least two integrating nodes (Ga, Gb) and the integration nodes (Ga, Gb) are connected to a device () for charge compensation, wherein the charge compensation device () comprises at least two SBI input transistors (M, M) which at a potential (Ua, Ub) of the integration nodes (Ga, Gb) which according to the amount exceeds an SBI threshold value (U) drive SBI current transistors (M, M) such that at both integration nodes (Ga, Gb) a compensating current (i) of the same level flows, wherein the source terminals of the SBI-current transistors (M, M) are not connected to a supply voltage (U) but are connected to a working voltage (U, U) (FIG.).
