    • Disclosed are a ramp signal generator and an image sensor. The ramp signal generator includes: a comparator comparing a first bias voltage input to a first input terminal and a second bias voltage input to a second input terminal and outputting a ramp signal from an output terminal; a ramp signal adjustment unit including a plurality of switched capacitors made up of switches and capacitors connected in series, and connected in parallel between a first input terminal of the comparator and an output terminal of the comparator; and a controller switching the switches of the plurality of switched capacitors to adjust the ramp signal output from the comparator such that the ramp signal becomes nonlinear over time.
    • 公开了一种斜坡信号发生器和图像传感器。 斜坡信号发生器包括:比较输入到第一输入端的第一偏置电压和输入到第二输入端的第二偏置电压并从输出端输出斜坡信号的比较器; 斜坡信号调整单元,包括由串联连接的开关和电容器组成的多个开关电容器,并且并联在比较器的第一输入端子和比较器的输出端子之间; 以及控制器切换多个开关电容器的开关以调整从比较器输出的斜坡信号,使得斜坡信号随时间变得非线性。
