This paper presents a methodology for analog designers to maintain their insights into the relationship among performance specifications, topology choice, and sizing variables, despite those insights being constantly challenged by changing process nodes and new specs. The methodology is to take a data-mining perspective on a Pareto Optimal Set of sized analog circuit topologies, then doing: extraction...
In this paper a theoretical model for the design of high efficient SOPA power amplifiers is deducted. Switching type power amplifiers do not suffer the efficiency decay with the crest factor compared with linear type amplifiers. Using the describing function analysis, an analytical model has been derived to cope with the hard non-linear specifications of a switching type amplifier. This speeds up...
The work focuses on a better understanding of the sub-quater micron ggNMOS device breakdown, compact modeling of the band-to-band tunneling enhanced substrate current and the observed gate hot hole injection current. Simple implications of the improved subbreakdown current model on the ggnNMOS model behaviour are shown. Finally, the observed TLP failure mode of the investigated devices is discussed.
