UWB radio module design for wireless sensor networks

Abstract

In this paper, we have designed an impulse-based ultra wideband (UWB) radio module for wireless sensor networks (WSN) applications. The UWB radio module includes transceiver block, baseband process unit and power management block. The transceiver block includes Gaussian pulse generator, wideband low noise amplifier (LNA), multiplier, integrator and timing circuits, which use 0.18um, 1P6M CMOS technology. The wideband LNA has a power gain of 10dB and minimum noise figure of 2.7dB. For transceiver block, the power consumption of transmitter is lower than 1mW while the receiver is about 23mW. The liquid-crystal-polymer (LCP)-based System-on-Package (SoP) technology will be used to implement the UWB radio module for low power, low cost and small size.

Energy Evaluation of PMCMTP for Large-Scale Wireless Sensor Networks

“…In the literature, several UWB transceivers have been proposed [21]- [26]. The power consumption of UWB transmitter varies from 2mW to 15mW and that of UWB receiver varies from 21.6mW to 50.1mW .…”

“…Energy conservation is no doubt the most important feature of a WSN. The average power consumption of a sensor node must be between 10-100 uW with a single 1.5 V AA alkaline battery to last the node for a lifetime of 1-5 years [4]. Communication is the most power consuming operation that a sensor node performs.…”
