The need for advanced silicon modeling in RF nanometer designs
May 1, 2005
By Karen Chow Nanometer technologies, while enabling functionality on a chip, bring a host of additional physical effects for the designer to consider. This is particularly the case with the latest standards in design, such as GSM/GPS/Bluetooth. The physical effects, in addition to re-spin costs in the million-dollar range, make verification indispensable to the mixed-signal generator....
Using behavioral models to drive RF design and verify system performance
Mar 1, 2005
By Colin Warwick and Mike Mulligan A new generation of software tools for model-based design is enabling
the creation of system-level models that system architects can use to
evaluate the RF design specification. These flexible design environments
allow information to flow top down and bottom up. Before, during and
after the circuitry for the components and modules is being designed,
the same system-level model can incorporate ever more refined
performance information in order to determine the impact on systemlevel
performance....
Effective Cascaded Intermodulation Analysis
Sep 1, 2004
By Rulon VanDyke A new simulation technique has been developed that empowers designers
to maximize intermodulation and noise performance while reducing analysis
time. Complicated, individualized, custom spreadsheets, math packages and ad
hoc tools are prone to error and unnecessary. This new simulation technique
leads to better designs, a quicker design phase and more revenue for the
company....
Fast Multitone Analysis of RF Transceivers
May 1, 2004
By George Estep, Pete Johnson & Vladimir Veremey Full-chain simulations using harmonic balance and fast envelope techniques enable fast and full characterization of modern integrated radio transceiver ICs with thousands of transistors....
Getting closer to a top-down methodology for RF SoC design
Mar 1, 2004
By Jean Oudinot The drive to fully integrate communications products onto a single chip has created the urgent need for an integrated RF SoC design flow. Until now the...
CDMA2000 RF system design software and spreadsheets
Jan 1, 2004
By Anitha Swaminathan Today's complex designs, particularly with the advent of digital communications standards such as code-division multiple access (CDMA2000), require a...
