A graph of burst noise or "popcorn noise".

Caption from Lundberg:

Figure 3: Typical popcorn noise, showing discrete levels of channel current modulation due to the trapping and release of a single carrier, for three different bias conditions

From original caption:

Figure 1. Typical random-telegraph noise signal.

Top Trace: Vgs = 1.4 V.

Middle Trace: Vgs = 1.6 V.

Bottom Trace: Vgs = 1.8 V.

Vds = 0.2 V for all traces.

Description:

A measurement system similar to that used in [M. Kirton and M. Uren, Adv. Phys., vol. 38, no. 4, p. 368, 1989.] was used to characterize the deep-submicron devices. Following amplification by a low-noise transresistance amplifier with a gain of 106, the drain current signal is input to an HP3561 Dynamic Signal Analyzer which performs a time capture. The mean capture time <τc> and the mean emission time <τe> are extracted from the RTS signal-vs-time data capture using a HP200 series computer. An MMR LTMP-4 low temperature microprobe was used to characterize devices across a range of temperatures. The LTMP has an operating temperature range of 80-400 K.
