Mos thermal noise

WebThe limiting noise mechanism in field-effect transistors is thermal noise of the conducting channel. The noise can be represented by a current generator i2 in parallel to the output. The value of i2 is calculated; for zero drain voltage the noise corresponds to thermal noise of the drain conductance, and for other bias conditions the noise at a given gate voltage … WebThis set of VLSI Multiple Choice Questions & Answers (MCQs) focuses on “Noise in MOS Devices”. 1. Noise in VLSI circuits mean: a) Unwanted signals that arise due to vibration in the passive circuits. b) Unknown signal that limits the minimum signal level that a circuit can process with acceptable quality. c) Signal which undergoes distortion.
