Panel casts doubt on MEMS for energy harvest Design How-To 3/14/2013 4 comments A panel on energy and MEMS at the MEMS Executive Congress Europe cast doubt on the use of MEMS for energy harvesters but despite this the audience showed themselves to be optimistic about prospects for the technology
ST returns fire over MEMS patents Design How-To 3/12/2013 2 comments MEMS supplier STMicroelectornics has gone to the International Trade Commission in the U.S. seeking an exclusion order against MEMS from rival InvenSense and some products that include these MEMS.
Startup builds 100-Gbps laser in CMOS Design How-To 3/4/2013 6 comments A low-cost tunable laser made in CMOS could transform the architecture of datacenters and the economics of metro and long-haul communications networks, according to its maker, a startup from Albuquerque, New Mexico.
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.
