摘要： Disclosed herein is a Complementary Metal-Oxide Semiconductor (CMOS) image sensor. The CMOS image sensor includes a pixel array, a frame memory, and an analog-to-digital converter. The pixel array includes N unit pixels for converting optical signals, caused by light, into electric signals. The frame memory eliminates offset voltage included in reset voltage and signal voltage transmitted from the pixel array and internal offset voltage, and performs Correlated Double Sampling (CDS) on the reset voltage and the signal voltage. The analog-to-digital converter converts an analog signal, transmitted from the frame memory, into a digital signal.

The output buffer circuit can obtain an output voltage having a high slew rate even though a smaller amount of a bias current than that required in a conventional output buffer is used. Therefore, the output buffer circuit can reduce power consumption. In the output buffer circuit with a compensation capacitive load, an input part has two input terminal receiving differential input voltage signals, and an output part increases a gain of the differential input voltages. A current source biases the output part, and a slew rate increasing part is connected to the output part and the compensation capacitive load. The slew rate increasing part includes a switching element to increase a slew rate of the output buffer circuit.
