RFCMOS Performance OverviewBuilds on low cost digital CMOS roadmapParameters that are scaling with 1/L are dramatically improving for example: fmax, fT, and Fmin
Digital scaling issues translate to RF/Analog issuesVdd not scaling = high tinv= limitations in gdsand self gain (gm/gds)
Double gate FINFET, asymmetric halos, and high K gates offer reliefNew materials introduction required by scaling may degrade 1/f noise
Layout must be optimized, especially W for multi-finger devices
Parameter Good News Bad Newsft ~ vsat / 2π L improves with 1/L Rs ultimately limitsfmax = (fT / 2)(gds (RG+RS) + 2πftRGCGD)-1/2 ~ ft (W/L) wide W limited by Rg long W
gm ~ vsat W Cox ~1/Ltinv, improves gm not scaling with L, limited by Rs < 45nm
Fmin = 1 + K*(f/fT)(gm(RG+RS))1/2 improves scaled W/L limited by Rg long W
gm/gds FINFETS, high K, asymetric halos new structures reguired
1/f Circuit innovation limiting impact
degrades with nitridi- zation and high K?
threshold matching - 33% degrade per litho generation

SummaryToday's challenges to move data at fast rates are greater than ever
Wired networking data rates pushing technology 10Gb/s => 40 Gb/s => 160 Gb/s Wireless data transfer rates 0.1 =>100 Mb/s as 3G moves to 4G protocols
SiGe BiCMOS processBase after gate now the standard to decouple thermal cycles and achieve high fT, fMAX
Varactors, MIMs, Resistors, and thick dielectric/metal modules for inductors & TlinesSiGe HBTs continue to improve fT = 210 -> 275 GHz, fMAX = 280 GHz
Fastest circuits built to date are SiGe BiCMOS (3.9 pS RO delay) Integration capability will push SiGe BiCMOS into more and more application areas
SiGe BiCMOS products in wireless and wired applicationsWired technology: TIA, Post-Amp, Modulator driver, SerDes, & Integrated SerDes Framer Wireless building blocks and systems: LNA, PA, VCO, Synthesizer, Transmitters and Receivers, 5 GHz LAN, GSM and CDMA chipsets, 3G, & GPS
