Imec demonstrates first sub-5mW, IEEE 802.15.4z UWB transmitter chip
Imec demonstrates first sub-5mW, IEEE 802.15.4z UWB transmitter chip Imec has showcased the first IEEE 802.15.4z impulse-radio ultra-wideband (IR-UWB) transmitter chip at the International Solid-State Circuits Conference (ISSCC). The device has been designed to strike a better balance between UWBâs accurate and secure ranging capabilities for indoor localization and the need for increased energy efficiency. Fabricated in 28nm CMOS (with an occupied core area of only 0.15mm²), the chip aims to enable the next generation of cost-effective, small form-factor UWB d...
