The RF noise in 0.18um CMOS technology has been measured and modeled. Compared to long-channel theory we find only a moderate enhancement of the drain and current noise for short-channel MOSFETS and, due to the gate resistance, a more significant enhancement of the gate current noise. The experimental results are accurately describe by a non-quasi-static RF model, based on channel segmentation. Experimental evidence is shown for two additional noise mechanisms: (i) avalanche noise associated with the avalanche current from drain to bulk, and (ii)j shot noise in the direct-tunneling gate leakage current.
