Long distance, low data-rate UWB communication for sensor network applications requires a highly energy efficient transceiver combined with circuit and system-level optimizations to maximize range. A custom pulsed-UWB transceiver chipset in 90 nm CMOS is presented that targets these aggressive specifications. The transceiver efficiently communicates at data rates from 0-to-16.7 Mbps in three 550 MHz-wide channels in the 3.1 to 5 GHz band by using pulse position modulation (PPM). The transmitter… CONTINUE READING
