Analog design oriented ultra-deep-submicron CMOS technology analysis

Based on the analysis of 65 nm MOSFETs characteristics with regards to analog design requirements, this paper firstly highlights the inaccuracy of known rules of thumb and simple relations used by designers to size their circuits and reach a compromise on their specifications. We secondly propose a more accurate approach for quick estimation of short-channel transistor sizing and compare it to existing approaches in the case of a wide-band low-power OTA.
