Paper Abstract

Noise is an important factor in determining the sensitivity of CMOS imagers at low light levels. Both device or transistor thermal noise and l/f noise are contributing factors, correlated double sampling reduces the effect of both thermal noise and l/f noise but is less effective in reducing l/f noise as sampling time increases. Techniques to simulate noise in sampling circuits have only recently become available and are compared here to the older analytical techniques.
