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.
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.
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
