Closed-form expressions predicting the self-resonance frequency with less than 5% error have also been developed.

The following CMOS technologies are characterized and compared: 0.18 /spl mu/m, 0.25 /spl mu/m, 0.35 /spl mu/m, 0.5 /spl mu/m and 0.8 /spl mu/m. The unity current gain frequency scales as one over the effective gate length. The minimum noise figure is less than 1.5 dB at 2.0 GHz for gate lengths less than 0.5 /spl mu/m for both nMOS and pMOS transistors. The total device width required for conjugate noise matching is 400 /spl mu/m and 50 /spl mu/m for the 0.8 /spl mu/m and 0.18 /spl mu/m gate length, respectively. The current required for a 1.9 GHz cascode LNA is 15 mA and 2.7 mA for the 0.5 /spl mu/m and 0.18 /spl mu/m CMOS processes, respectively. This reduction in current is due to the fact that g/sub m//I/sub ds/ for a 0.18 /spl mu/m process is 25 V/sup -1/ whereas it is equal to 5 V/sup -1/ for a 0.5 /spl mu/m process. The advantage of using pMOS transistors is illustrated in a 1 volt RF front-end receiver.","PeriodicalId":20702,"journal":{"name":"Proceedings of the IEEE 2000 Custom Integrated Circuits Conference (Cat.

The method, while only suitable for offline computation, is more general than the established sigma-delta encoding technique, due to its capacity to take into account complex specifications and design trade-offs. Signal generation is formulated as a linearly constrained, convex, integer quadratic programming problem which is solved through an application specific branch-and-bound algorithm. The optimization method is illustrated with a fractional-N frequency synthesizer based modulator design example.","PeriodicalId":20702,"journal":{"name":"Proceedings of the IEEE 2000 Custom Integrated Circuits Conference (Cat.
