Abstract :
This paper presents criteria for the onset of NQS effects derived from time transient device simulations and S-parameter measurements. For the first time it has been proved that e.g, a 10 μm NMOS transistor can be described up to 27 MHz and a 0.2 μm device up to 46 GHz by the quasistatic approach while the accuracy of the description of the inversion layer charge is still 99%
