Claim 0:
1. An image sensing device comprising:
a current supply circuit coupled between a supply terminal of a first voltage and a pair of output terminals;
an input circuit coupled between the pair of output terminals and a common node, and suitable for receiving a pixel signal and a ramp signal; and
a mirroring circuit coupled between the common node and a supply terminal of a second voltage, and suitable for compensating for an operating current, which flows between the common node and the supply terminal of the second voltage, based on the operating current when generating the operating current by mirroring the reference current, wherein the mirroring circuit compensates for the operating current by adjusting a compensation current when the reference current is changed.
