Good vibrations for energy harvesting Teardown 11/10/2008 3 comments The combination of high-power-density piezoelectric element design with a high-efficiency converter takes energy-harvesting out of the lab to address the problem of powering remote and embedded devices.
Shedding light on solar cell technology Teardown 11/10/2008 3 comments It's clear that solar energy harvesting is poised to go mainstream, but it's not clear which of the many diverse technologies vying for dominance in this emerging market will take precedence.
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.
