A self-synchronized, crystal-less, 86µW, dual-band impulse radio for ad-hoc wireless networks

Abstract

An 86µW, 150Kbps, self synchronizing 3.5–4.5GHz UWB IR transceiver is presented. Synchronous receiver duty cycling of 0.5% is enabled without a crystal through a pulse coupled oscillator (PCO) network that establishes timing and allows multi-node multi-hop communication. The synchronization scheme is supported by implementation of low power oscillator and timing circuits to control duty-cycling. Our FCC compliant transceiver uses OOK modulation and has a receiver sensitivity of −86dBm.
