In accordance with the present invention, the upper and lower DC link capacitors are charged through different paths, respectively. Accordingly, a control for DC link voltages is enabled to achieve a reduction in voltage ripple while minimizing a degradation in performance.

Abstract: A complementary metal oxide semiconductor (CMOS) image sensor includes a photodiode, a switch and a comparator. The switch transfers a sensing signal to a sensing node from the photodiode. The comparator, which is directly connected to the sensing node, compares the sensing signal of the sensing node with a reference signal. The comparator outputs a signal corresponding to a voltage difference between the sensing signal and the reference signal.

Abstract: In a plasma display and a driving method thereof, a sustain pulse of a high level voltage is supplied to a scan electrode or a sustain electrode during a sustain period using a capacitor charged to a voltage corresponding to a voltage difference between a high scan voltage and a low scan voltage. A low-voltage capacity transistor is connected between a power source and the scan electrode, the power source supplying a high level voltage to the scan electrode. Using the low-voltage capacity transistor results in reduced driving circuit costs and, in addition, the number of times that a transistor supplying the high scan voltage to the scan electrode and a transistor supplying the low scan voltage to the scan electrode is reduced, thereby reducing ElectroMagnetic Interference (EMI).
