Cover
Feature: A new approach for simultaneous analysis of phase lock loops
and voltage controlled oscillators.
This article reviews a few
design considerations when developing phase lock loops and discuss
the importance of performing measurements in design verification to
ensure the design objectives are met.
Clocking
ADCs with Phase Locked Loops
As receivers cope with higher bandwidths in an increasingly crowded
frequency spectrum, higher performance levels are required of the
Analog to Digital converter (ADC). Higher input frequency and higher
resolution converters are required to meet the demands of the
receiver system.

Arabian Microwave Radios Can Stand the
Heat
The heat intensifies rapidly at sunrise and bakes the earth until
sunset. Ambient temperatures in the interior of 54 degrees Celsius
(130 degrees Fahrenheit) or more are common on the hottest days. This
is a place for man and beast to take shelter from the sun during the
hottest months.But the nation's microwave communications networks do
just fine.

RF
Wafer Testing - An Acute Need, and Now
Practical
Leading semiconductor producers have recently conceded that wafer
level RF measurements are acutely needed to develop and produce
advanced ICs. To a certain degree, this flies in the face of the 2003
recommendations by the ITRS Technical Working Group for Modeling and
Simulation. Yet, accurate parameter extraction for HF circuit
modeling at 1 - 40 GHz and for RF compact model verification has
become essential. This challenge is increasing for
high-performance/low-cost digital, RF, and analog/mixedsignal devices
as the industry progresses toward the 65nm node and
beyond.

World
Use of accurate and reliable wireless communications test solutions
and products can decrease cost and ensure time-to-market windows are
met.
