ISSCC 2021: MIT links silicon chips at 100Gbit/s with dielectric ribbon

In a silicon-compatible parallel to fibre optics, MIT is using polymer-based ribbon waveguides to carry data between chips at 105Gbit/s – waveguide dimensions and material are chosen so that it propagates electromagnetic radiation between 200 and 335GHz, over 300mm of waveguide. To handle suitable sub-Thz frequencies, transmitter and receiver were made on a 130nm SiGe BiCMOS process ...

LCD driver for 368 segments in vehicle dash

Epson is aiming at vehicle instrument clusters with a greyscale segment LCD driver for up to 368 segments. “The amount of information that needs to be shown on instrumental cluster displays is increasing as vehicles gain additional features and functions,” according to the company. “On the other hand, larger displays with higher definitions increase costs. For this reason, ...
