5 RF and AMS Technologies for Wireless Communications Working Group 5 Expected updates in the following areas : –GaN : Reflect higher level of progress –CMOS Depending strongly on updates in LSTP roadmap (RF CMOS follows LSTP roadmap with 1 year lag) Introduction of high-k / metal gate important for analog/RF CMOS : –1/f noise –Matching performance –Leakage 2006 Requirement Tables Updates

6 RF and AMS Technologies for Wireless Communications Working Group 6 Assembly & Packaging –Embedded passives requirements to be provided to Assy&Pkg : – volume product (e.g. GSM) – low power/short range product (e.g. Bluetooth) – mm-wave product (car radar or 60 GHz UWB) –Assy&Pkg want to expand the RF part of their chapter Request for discussion on boundary between Wireless chapter and Assy&Pkg Design –Discussed update of SiP design flow : – Focus has been on SoC design flow – Design will check with EDA vendors –Discussed impact of digital radio on analog/RF CMOS requirements table (to be continued) 2006 Cross-TWG Focus

7 RF and AMS Technologies for Wireless Communications Working Group 7 Test –Had discussion on cost-effective testing of RF ICs – Follow-up in July Meeting –Discussed evolution of number of RF pins : – Impact of multi mode – Re-use of blocks (broadband) PIDS –Update needed for LSTP roadmap –Update needed for high-k / metal gate introduction –I/O devices are not covered in their roadmap : – Re-use for analog versus dedicated optimization 2006 Cross-TWG Focus

8 RF and AMS Technologies for Wireless Communications Working Group 8 Signal isolation Optimizing analog/RF CMOS devices with scaled technologies: mismatch, 1/f noise, and leakage with high-k gate dielectrics ; voltage gain High density integrated passive element scaling and use of new materials: Q-factor value for inductors matching and linearity for capacitors High range varactors for UWB Reduced power supply voltages: degradation in SNR and signal distortion performance for AMS Reduced device breakdown voltage in scaled technologies Compound semiconductor substrate quality, especially for SiC Larger size compound substrates [GaAs, SiC and InP] for lower chip costs and compatibility with silicon processing equipment Difficult Challenges (1)

9 RF and AMS Technologies for Wireless Communications Working Group 9 Epitaxial layers in compound semiconductors engineering to relieve stress in heteroepitaxy Non-linear and 3D Electromagnetic models for accurate design and simulation Difficulty and cost of integrating various analog/RF and digital functions on a chip or in a module CAD solution for Integrated Radio SIP design (chip, passive, component, package, tool compatibility, model accuracies) Difficult Challenges (2)
