Plessey reborn as UK's newest semiconductor firm

Many of us remember the Plessey name from the range of RF ICs it made back in the 1980s e.g. the SL640, SL641 and the SL6440. In their day they were ahead of the time. Many an SSB transceiver was built around these ICs. Well, Electronics Weekly reports Plessey is back.
"Plessey Semiconductors, one of the most renowned names in the UK’s semiconductor history, has been relaunched as a chip business operating from the original Plessey CMOS fab at Roborough in Plymouth.
Plessey Semiconductors has been created out of Plus Semi, a company set up to acquire the manufacturing facilities of two former Plessey fabs in Swindon and Roborough."
Electronics Weekly is available online and is well worth checking.

Power harvesting IC - runs off 20mV produces 5V

This week's Electronics Weekly has a link to Linear Technologies new power converter IC (LTC3108) that can run from 20mV and deliver 5V. It is designed to be used with Peltier effect devices and similar sources of low voltages, but it could be used with the DC power derived from a crystal set.
