Design Challenges Of High-Speed Wireline Transmitters


By Samad Parekh and Noman Hai The need for higher bandwidth networking equipment as well as connectivity in the cloud and hyperscale data centers is driving the switch technology transition from 25T (terabytes) to 50T and soon to 100T. The industry has chosen Ethernet to drive the switch market, using 112G SerDes technology today and next generation architectures being designed to operate at... » read more

Power/Performance Bits: Aug. 18


Flexible, hole-filled films Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) and Hongik University propose a simple way to make flexible electrodes and thin film transistors last longer: adding lots of tiny holes. A major problem with flexible electronics is the formation of microscopic cracks after repeated bending which can cause the device to lose its conducti... » read more

Power/Performance Bits: July 30


100GHz transceiver Engineers at the University of California Irvine built a new wireless transceiver that works above 100 gigahertz. The 4.4-millimeter-square silicon chip, called an "end-to-end transmitter-receiver," uses a digital-analog architecture that modulates the digital bits in the analog and radio-frequency domains to process digital signals quickly and energy-efficiently. "We cal... » read more
