The emerging field of ad-hoc wireless sensor networks [1] requires small, highly integrated, inexpensive transceivers with very low power consumption (constrained to 1mW average to enable energy scavenging). This transceiver combines a superregenerative architecture with bulk acoustic wave (BAW) resonators [2] to reduce the power consumption [3], increase the level of integration, and provide selectivity. The principle of super-regeneration achieves a high-RF gain at low bias currents through discrete sampling of the RF input signal with a periodically cycled RF detector oscillator.
