Abstract
This paper presents an ultrasound (US) transceiver including a transmitter and a receiver for underwater wireless sensor nodes, where low-power operation is desired to extend the life-time of the network. A system-level analysis of the underwater communication has been performed by taking into account the underwater propagation and the medium charac-teristics to show their impact on the overall performance. In addition, a low-noise amplffier using an inverter-based topology has been introduced to ensure power efficiency of the receiver, where a bulk-feedback method is proposed to stabilize the output bias point of the inverter. Simulation results show that the proposed transceiver has a scalable power consumption from 1.95μ W to 10.4μ W while achieving 100μ V to 20μ V sensitivity at a 10-3 BER level.
