> Advances in high speed circuit design, execution, and underlying
> technology will be critical to meeting the communications requirements of
> future wireless,  wired data communication, and backplane applications. In
> the wireless arena, the recent development of advanced SiGe transistors
> with fT and fmax values exceeding 200 GHz may enable low cost
> implementation of very high data rate wireless communications systems
> operating in the 60 GHz band, as well as low cost automotive radar systems
> operating in the 77 GHz band.  At lower frequencies, such as in 2.4 or 5
> GHz bands, CMOS as well as SiGe are vying for market share while meeting
> stringent cellular and WLAN system requirements. For future wired data
> communications systems, techniques enabling the achievement of higher data
> rates will be of extreme importance.  Finally, in the backplane
> environment, advanced digital CMOS technology must be applied to
> increasingly challenging analog problems to achieve ever-higher data rates
> while meeting strict power budgets.  In this talk, high speed circuit
> design work in the Communication Technology department of IBM Research
> will be described, focusing on  four main areas, namely, mm-wave wireless,
>  comparison of W-CDMA RFIC designs in CMOS and SiGe, ultra-high speed
> serial data communication, and backplane I/O.  In each area, the key
> high-level design goals and challenges will be presented, followed by
> presentation of circuit design and hardware results for critical
> sub-blocks.
