Imec showed the first IEEE 802.15.4z impulse-radio ultra-wideband (IR-UWB) transmitter chip at ISSCC. The device strikes a balance between UWB’s 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 ...
