Abstract: There is provided an LED circuit including a light emitting unit including a plurality of light emitting diodes; and a switching unit switching to apply only positive voltage of an AC power supply to an anode of the light emitting unit. Through this, the LED circuit can reduce complexity of a driving circuit. Further, lifespan and efficiency of the LED circuit may be improved since an electrolytic capacitor and a bridge circuit are not used. Further, any one light emitting diode may be prevented from determining the lifespan of all of the light emitting diodes since all of the light emitting diodes are driven at all times, thereby improving the lifespan of the light emitting diode.

Abstract: In a unit pixel of a CMOS image sensor which compensates for a dark current generated in a photo diode to enhance its driving range, the photo diode generates a charge in accordance with a received light amount. A drive transistor has a gate for receiving the charge in the photo diode to output as an electrical signal, and a drain to which a power voltage is applied. A saturation detector receives a gate voltage of the drive transistor and judges the drive transistor saturated if an output voltage is smaller than a preset reference voltage. A switch connects or disconnects between the power voltage and the gate of the drive transistor in response to the judgment of the saturation detector.
