Abstract

This paper explores the design and implementation of a low-power two-channel transceiver using micromachined resonators. Wireless sensor networks require transceivers that are small, cheap, and power efficient. RF-MEMS resonators are utilized to accommodate these constraints. The prototype 1.9GHz transceiver, designed in 0.13 μm CMOS, operates at 1.2V and consumes 3mA in receive mode and transmits 1.6dBm with 17% efficiency. The two 40kb/s channels achieve a sensitivity of -78dBm with a 10 μs receiver start-up time.
