Abstract
An ultra-low power transceiver for battery-free wireless sensor networks is presented. The receiver uses a modified super-regenerative architecture with BFSK modulation to improve speed and sensitivity. Transmitter efficiency is improved by using a power oscillator to directly drive the antenna. The entire transceiver achieves a total link energy less than 1nJ/b and can communicate over distances as large as 20m, making it the lowest power integrated transceiver to date.
