Project aims to cut conversion losses by 50% Research 12/15/2010 3 comments The Neuland project, part funded by the German Federal Ministry of Education and Research (BMBF), has been set up to explore the efficient use of electricity from renewable sources based on novel semiconductor materials.
Intelligent multiplexer upgrades automotive lighting high side drivers Design How-To 12/10/2010 1 comment Control and diagnostics of lighting functions are some of the growing tasks performed by modern body control modules. An intelligent multiplexer would provide a solution to their ever increasing requirements in terms of pulse width modulation channels, diagnostics, and system reliability in automotive lighting applications.
Solutions for nonlinear characterization of high-power amplifiers Design How-To 12/6/2010 4 comments High-power RF amplifiers are used in telecommunications, biomedical, and military systems. With output power levels ranging up to 1 kW, these amplifiers are typically designed to operate near or into compression in order to provide the maximum output power possible. Designing high-power amplifiers requires a detailed analysis of its nonlinear behavior.
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.
