Claim 1:
2. The image sensing device of claim 1, wherein the mirroring circuit includes:
a first mirroring element coupled between an input terminal of the reference current and the supply terminal of the second voltage, and suitable for generating a bias voltage corresponding to the reference current;
a second mirroring element coupled between the common node and the supply terminal of the second voltage, and suitable for generating the operating current corresponding to the reference current based on the bias voltage;
a compensation element coupled between the supply terminal of the first voltage and an output terminal of the bias voltage, and suitable for compensating for the bias voltage based on the operating current; and
a current source coupled between the output terminal of the bias voltage and the supply terminal of the second voltage.
