White space transceiver from Cambridge

Neul has announced its first transceiver chip for ‘white space’ communications in 470-790MHz UHF TV bands. Called Iceni, the chip is intended for secure non-line-of-sight machine-to-machine (M2M) communications. Both 6 and 8MHz channel bandwidths are supported, and “adaptive digital modulation schemes and error correction…

ST says low power comparator is fast

STMicroelectronics has a high-speed voltage comparator with current consumption of less than 500µA.

This is significant, says ST, because of the chip’s 8ns propagation delay at a current consumption of only 470µA at 5V. As well as signal-conditioning applications in telecoms, fast-response comparators can…
