Introduction to Ultra Low Power Transceiver Design

Abstract

Design of radios with ultra-low-power consumption can enable many new and exciting applications ranging from wearable healthcare to Internet of Things devices and beyond. Achieving low power operation is usually an exercise in trading-off important performance metrics with power. This chapter presents an overview of state-of-the-art narrowband architectures and techniques that achieve ultra-low-power operation, and concludes with a section that benchmarks recent state-of-the-art designs in order to illustrate power-performance trade-offs.

REFLOOD: Reactive routing protocol for wake-up radio in IoT

“…Throughout this work, we will assume that the WuR receiver can work at both 1 kbps or 10 kbps. However, increasing the data rate too much reduces sensitivity [13].…”

Ultra Low Power Wake-Up Radios: A Hardware and Networking Survey

“…13 shows the data rate of WuRxs with respect to their 1566 power consumption and signal modulation techniques. Since, 1567 power is inversely proportional to data rate, it is generally pos-1568 sible to increase the data rate with little power overhead [124], 1569 however, communication distance will be short. For example, 1570 it does not cost much in terms of power to increase the mod-1571 ulation rate from 1 kbps [50] to 100 kbps [83] in an OOK 1572 receiver.…”
