Title:
固体撮像装置、画素信号読出方法
Document Type and Number:
Japanese Patent JP4144535
Kind Code:
B2
Abstract:
The levels of the power supply and the ground are kept constant against a parasitic resistance by keeping the constant current of an amplifier irrespective of the size of a pixel signal and the gain of the amplifier in this case in an image signal reading circuit system having the amplifier arranged to each column. The amplifier has a limiter at an output terminal thereof which limits an output voltage of the amplifier to a range for keeping the constant consumption-current.
