A Novel Extra Low IF Receiver for the GSM Band
Design How-To  
12/20/2001   Post a comment
Authors from the University of Athens, Greece, describe the design of an extra low IF (455 kHz) receiver topology for wireless systems. Overall receiver performance is evaluated in terms of noise figure, inter-modulation, blocking requirements, SNR, and C/I.
CMOS VCSEL Driver Design at 1Gbits/s for High-Speed Optical Communication Applications
Design How-To

Modeling high-speed mixed-signal chips remains a "black art" for many designers. Using a 1 Gbit/s laser-driver chip in a 0.13 µm CMOS process, Russ Kramer of Agilent EEsof EDA shows how you can include substrate parasitic effects to more accurately model your design.
A Time-Domain-Based Technique for Noise Measurements
News & Analysis  
12/14/2001   Post a comment
Although electronic noise is often a critical design parameter in an analog system, evaluation of noise performance of circuits that perform a frequency translation from RF to baseband is not easy to do. Torben Larsen and colleagues from Aalborg University in Denmark describe a time-domain-based technique to determine the noise factor of a device with a low desired output frequency.
