T
he role that the cellular phone plays
in our daily lives
is constantly evolving. Conceived as a
" mobile " telephone to contrast with a
" tethered " telephone, the cell phone
functions as a personal assistant, a
music player, and a camera, while expanding its primary role as a wireless
data transceiver. On average, there
is more than one mobile phone per
person in this world. Thanks to this
all-pervasive reach, several essential
services-for example, banking and
health care-are now delivered to
end users through their cell phones.

cellular communication are continually evolving to support this changing
landscape in a power-and spectralefficient manner. Mobile technology has witnessed five generations of
evolution: from the mobile-phone era
ushered in by 2G to the future smartphones that will be powered by the enhanced spectral efficiency of 5G.
Innovative circuit-techniques and
advances in device fabrication have
enabled the integration of discrete
component radios onto a single piece
of silicon. In parallel, the scale of integration has driven down the size,
power consumption, and cost of these
radios and has played a pivotal role
in enabling the rapid growth of wireless communication. In response to
the burgeoning interest in industry
and academia, several tutorials at the
IEEE International Solid-State Circuits
Conference (ISSCC) have addressed
diverse aspects of radio-frequency integrated circuit (RFIC) design [1]-[3].
With the introduction of 5G phones
just around the corner, a tutorial
[4] describing the evolution of multimode cellular RFICs-starting from
specifications leading to circuits-
was presented at ISSCC 2020. This
article is an abridged version of the
material presented in [4].
Network providers drive the development of new cellular standards to
improve the end-user experience while
supporting a larger number of customers. However, high deployment costs
prevent network providers from rehauling the entire infrastructure every
time a new standard is introduced. A
