Abstract--Digital logic integrated circuits are advancing
toward ever higher speeds of operation. Clock frequencies already
exceed 1 GHz in some Si CMOS-based consumer products, and
even higher speeds are attainable in specialized technologies, such
as those based on GaAs, InP, and SiGe bipolar and field-effect
transistors. Digital approaches may be used to carry out a variety
of functions important in microwave systems, including signal
generation, filtering, and frequency conversion. The digital
implementation provides a variety of potential benefits, including
lack of sensitivity to aging and component inaccuracies, flexibility,
and programmability. The dynamic range and degree of non-
linearity can be specified by design. Signal storage and memory
functions are easily accomplished. Single-chip integration of
digital and microwave systems are also facilitated. The application
