Context
A Random Telegraph Signal (RTS) is a random process that switches alternatively between two or more discrete levels. This phenomenon has been observed in many electronic devices and can have several different physical origins. Several names are used to describe it : RTS, Random Telegraph Noise (RTN), burst noise, popcorn noise, Variable Junction Leakage (VJL) and some application specific names such as blinking pixels in CIS or Variable Retention Time (VRT) in DRAMs.
In Solid State Images Sensors, RTSs lead to bright pixels that seem to be turned on and off randomly. Such pixels are generally called blinking pixels. Because of the constant progress in the reduction of dark current and noises, this parasitic behavior is becoming the limiting factor for a growing number of high-end applications.
