Burst noise in the HAWAII-1RG multiplexer

Abstract

Burst noise (also known as popcorn noise and random telegraph signal/noise) is a phenomenon that is understood to be a result of defects in the vicinity of a p-n junction. It is characterized by rapid level shifts in both positive and negative directions and can have varying magnitudes. This noise has been seen in both HAWAII-1RG and HAWAII-2RG multiplexers and is under investigation. We have done extensive burst noise testing on a HAWAII-1RG multiplexer, where we have determined a significant percentage of pixels exhibit the phenomenon. In addition, the prevalence of small magnitude transitions make sensitivity of detection the main limiting factor. Since this is a noise source for the HAWAII-1RG multiplexer, its elimination would make the HAWAII-1RG and the HAWAII-2RG even lower noise multiplexers.

“…In this particular figure, popcorn events endure for several frames (100s of seconds). In other pixels, popcorn is sometimes detected on timescales shorter than 12 seconds (Rauscher, 2004;Bacon et al, 2005). Conversion gain for this figure is about g = 1.3 e − /ADU and the frame rate is about 10.7 seconds per frame.…”

“…One interesting phenomena seen in the near-IR JWST detectors is popcorn noise (see Figure 9), or "popcorn mesa noise" (Rauscher, 2004;Bacon, 2005). The popcorn mesa noise appears as an almost digital toggling between states as charge integrates up during long, dark exposures.…”

“…Figure 1) in the gradually rising temperature data above the exponential fit in both Figures 2 and 3. The Si diode temperature sensor on the SCA motherboard exhibited Random Telegraph Signal (RTS) noise (also known as burst noise or popcorn noise, see Bacon et al 8 ) as evidenced by the dual level nature of the data in Figure 3. The RTS noise is seen in only this small Si diode temperature sensor on the SCA motherboard and not in any of the larger Si diode temperature sensors employed by the University of Rochester or in the cernox temperature sensors.…”
