This book discusses the trade-offs involved in designing direct RF
digitization receivers for the radio frequency and digital signal
processing domains. A system-level framework is developed,
quantifying the relevant impairments of the signal processing
chain, through a comprehensive system-level analysis. Special
focus is given to noise analysis (thermal noise, quantization
noise, saturation noise, signal-dependent noise), broadband
non-linear distortion analysis, including the impact of the
sampling strategy (low-pass, band-pass), analysis of
time-interleaved ADC channel mismatches, sampling clock purity and
digital channel selection. The system-level framework described is
applied to the design of a cable multi-channel RF direct
digitization receiver. An optimum RF signal conditioning, and some
algorithms (automatic gain control loop, RF front-end amplitude
equalization control loop) are used to relax the requirements of a
2.7GHz 11-bit ADC.

A two-chip implementation is presented, using BiCMOS and 65nm CMOS
processes, together with the block and system-level measurement
results. Readers will benefit from the techniques presented, which
are highly competitive, both in terms of cost and RF performance,
while drastically reducing power consumption.
