1.有点像把噪声当失调处理了
2.可能对于随机失调有一定的消除作用

Correlated double sampling (CDS) is a method to measure electrical values such as voltages or currents that allows removing an undesired offset.
It is used often when measuring sensor outputs.
The output of the sensor is measured twice: once in a known condition and once in an unknown condition. The value measured from the known condition is then subtracted from the unknown condition to generate a value with a known relation to the physical quantity being measured.
