| 摘要 |
The present invention comprises: a photodiode which accumulates electrons when light is received; a gate transistor which determines transfer of the electrons accumulated in the photodiode; an accumulation transistor which includes a parasitic capacitor in which electrons transferred through the gate transistor are accumulated, and transfers a voltage level according to the amount of the accumulated electrons; and a control unit which controls the gate transistor to be operated several times with respect to a certain phase of an optical signal such that electrons are accumulated in the parasitic capacitor. |
