Today’s electronic communication possibilities and applications are endless. However,
only 150 years ago, the concept of the telephone was unknown. The history of
electronic communication begins in the nineteenth century with the telegraph, and
a couple of years later, the telephone. At the end of the same century, the foundations
of wireless electronic communication were established. In the beginning, these
electronic systems were bulky and impractical due to large components like vacuum
tube amplifiers. Thanks to the invention of the transistor and the integrated microprocessor,
these communication systems could be miniaturized and integrated into
portable systems that we all use today, like smartphones, laptops, and tablets.
History has also taught us that the demand for data rate over wireless channels
rapidly increases, from several kilobits per second in the early 1990s to hundreds
of megabits in today’s high-speed wireless links. But even these high-speed links
cannot support the applications of the (near) future like wireless uncompressed (ultra)
high-definition video streaming or gigabit wireless LAN, for which data rates in the
order of 10 Gb/s and even higher are required. Therefore, new solutions have to be
developed to support these high-data-rate links, today and in the future. One of the
most promising solutions is to shift the wireless carrier frequency from the currently
used microwave bands (e.g., 2.4, 5 GHz) toward the millimeter-wave frequency
spectrum (60, 85, 94, 120 GHz), where high modulation bandwidths are available,
which can support gigabit-per-second wireless data streaming.
This work focuses on the development of circuit and system design techniques
for millimeter-wave wireless communication systems above 90 GHz and fabricated
in nanometer-scale CMOS technologies. The scaling of CMOS technologies over
the past decades has led to transistors with gate lengths in the nanometer scale range.
Thanks to this scaling, the speed of the MOS transistors has also increased to a
maximum frequency of oscillation above 300 GHz for the latest technology nodes.
So CMOS has become a millimeter-wave technology, but with the great advantage
of high integration capabilities.
Although the speed of the CMOS transistors has increased, the target operation
frequency of the circuits in this work (above 90 GHz) is still close to the technology’s
maximum frequency of oscillation. So coping with a low power gain is one of the
