Chevy Volt flap: What's the big deal? Automotive DesignLine Blog 10/18/2010 41 comments Some fans of electric cars and hybrids, and a few folks in the press, are getting all in a knot about Chevy actually having a "direct link" from the gas engine to the wheels in its Volt "range-assisted" electric car. Well maybe its just good engineering.
LinkZero-AX switching IC cuts standby waste to zero Product News 10/14/2010 Post a comment LinkZero-AX from Power Integrations is a new integrated offline switching IC that enables designers to achieve 0.00 watts of standby energy consumption in auxiliary power supplies. Commonly used in such products as major appliances, TVs, and remotely-controlled electronic lighting ballasts, auxiliary power supplies continuously draw power as long as the product is plugged in, resulting in significant standby energy waste.

T&M gets dedicated designline Test & Measurement Designline Blogs 10/4/2010 1 comment Welcome to the Test & Measurement Designline, the latest addition to the EE Times Group's 'heads down' communities designed to help engineers tackle practical, technical and software challenges to bring product specification to reality.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
