Abstract :
This work describes a method of implementing a fully-integrated ultra-low power (ULP) radio for wireless sensor networks (WSN). This is achieved using a specific medium access control (MAC) protocol, employing a duty- cycled wake-up radio and a crystal-less clock generator, and an ad-hoc modulation scheme (Impulse Radio) with a bandwidth of 17.7 MHz in the 2.4 GHz - ISM band. The total average power consumption is expected to be less than 100 muW.
