An Ultra-Low-Power interference-robust IR-UWB transceiver chipset using self-synchronizing OOK modulation

Abstract

A short-range 1 Mb/s 3.8 GHz IR-UWB transceiver in 90 nm CMOS uses 1.5 pulse/bit synched-OOK modulation, enabling low-complexity 200 pJ/b digital demodulation and synchronization. An interference-robust asynchronous energy detector receiver can tolerate interferers up to -5 dBm. The power-gated oscillator-based transmitter has a power efficiency of 10.4%.
