Signal generator and method for generating signals for reducing noise in signals
摘要：
A CMOS image sensor may include an active pixel sensor array and a noise canceller array corresponding to the active pixel sensor array. A method of operating such an CMOS image sensor may involve generating a varying reference signal that mirrors noise external to the active pixel sensor array, outputting the varying reference signal to the noise canceller array, and using the varying reference signal in the noise canceller array to cancel noise both internal to and external to the active pixel sensor array.

CMOS图像传感器可以包括与有源像素传感器阵列相对应的有源像素传感器阵列和噪声消除器阵列。 操作这种CMOS图像传感器的方法可以包括生成改变的参考信号，其反射有源像素传感器阵列外部的噪声，将改变的参考信号输出到噪声消除器阵列，以及使用噪声消除器阵列中的变化参考信号 消除有源像素传感器阵列内部和外部的噪声。
