Lkj. Vandamme et al., Anomalous behaviour of the current noise in long-narrow-channel MOSFETS and its interpretation, SOL ST ELEC, 43(4), 1999, pp. 697-700
An anomalous behaviour of noise in n-type CMOSFETs with narrow, long channe
ls has been found. At fixed drain voltage, biasing the device well in satur
ation, the noise current abruptly decreased by more than an order of magnit
ude with increasing gate voltage well above the threshold voltage. We will
prove that the effect is due to the strong resistance noise of the parasiti
c source series resistance. An earlier, controversial result of Park and Va
n der Ziel can be reinterpreted in the same way. (C) 1999 Elsevier Science
