Abstract
In the last decade, the wireless communication revolution has spawned a revival of interest ill
the design and optimization of radio transceivers. Recently batterv-operatcd wireless communi-
cation has become popular for 1l1<.UIY applications. The emergence of extremely low-cost wireless
communication nodes with battery lifetimes extending over years is expected to usher ill a new
generation of wirele s control and monitoring applications that were inconcei vable in the past. For
example, low-rate wireless personal area network (LTI- \VPAN) is a low-complexity network optiuiized
for low-power hart range applications which require extremely lowpower so c)’:’to la..st for
years without battery recharge or replacement. Due to the technology scaling. the digital part of
the transceiver is coutinuously enhancing in performance (faster, and/or uiore importantly lower
power), yet the power consumption of the RF front-end (as the case with most analog circuits)
has not scaled down so dramatically. In this thesis. we present several ideas to help lowering the
power consumption of three most power consuming blocks of an TIF transceiver Iron-end namely;
the frequency divider, the power amplifier. and the local oscillator. All designs are implemented
on TSMC 0.13/tffi lP8M, UTM CMOS-RF proces , and most. of them are verified on the
layout level. In the frequency divider section. t.he prescalcr has to operate at the RF frequency
and thus consumes a lots of power. The thesis Iocu C5 on the u c of injection locking techniques
to help lowering the power consumption of the prescaler achieving Figure Of Merit (F’Oi\[) over
150 G H =/m 1V. As for the power amplifier. maximizing the efficiency is a key factor ill loweri ng
the overall power consumption of the transceiver. In the thesis. we present a high efficiency (over 50%) compact, integrated, and inductor-Ies: class-D RF power amplifier. The third component
is the local oscillator. which also consumes significant portion of t IH’ front-end power. Here, our
focus is on the possible use of (\11 Automatic Amplitude Control loop (AAC loop) to continuously
keep the oscillator running at the lowest amount of current, with the smallest possible supply
voltage, but at the same time maintaining a high figure of merit (around Iv4dB).
