Multiplying energy sources to power demanding smartphones Design How-To 3/25/2011 6 comments In the recent years the semiconductor industry has made amazing progresses in delivering higher performance at lower power consumption. However, the gap between the energy need and availability not only persists, but is continuously widening. One way to address this dilemma is to design bigger or denser batteries for the phones, impacting cost or weight or both, but this is not enough to effectively close the energy gap. A smarter way is to multiply the sources of available energy and recharge t
Taiyo Yuden BRHL2518 power inductor Product News 3/16/2011 Post a comment Taiyo Yuden's latest wire-wound chip power inductor measures 2.5 mm x 1.8mm x 1.5 mm, reducing volume by 65% and enhancing DC-DC converter efficiency by 5% compared with its previous generation.
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.
