1. A light receiving device comprising:
a light receiving element including an anode electrode and a cathode electrode;
a readout circuit configured to read out a signal from the light receiving element;
a resistor including a first end and a second end, the first end being electrically connected to one of the anode electrode or the cathode electrode of the light receiving element;
a first transistor including a first electrode, a second electrode and a gate electrode, the first electrode being electrically connected to the second end of the resistor and the second electrode being electrically connected to the readout circuit to provide the signal from the light receiving element to the readout circuit; and
a second transistor including a first electrode, a second electrode and a gate electrode, the first electrode being electrically connected to the second end of the resistor and the first electrode of the first transistor, the second electrode being connected to a reference potential, wherein
the first transistor is a first type, and the second transistor is a second type that is different from the first type.
