Abstract
A 1-Mb/s 916.5-MHz on-off keying (OOK) trans- ceiver for short-range wireless sensor networks has been designed in a 0.18- m CMOS process. The receiver has an envelope de- tection based architecture with a highly scalable RF front-end. Untuned RF circuits are leveraged and optimized in the receiver to achieve superior energy efficiency compared to tuned RF circuits. The receiver power consumption scales from 0.5 mW to 2.6 mW, with an associated sensitivity of 37 dBm to 65 dBm at a BER of 10 /51. The transmitter consumes 3.8 mW to 9.1 mW with output power from 11.4 dBm to 2.2 dBm. The receiver achieves a startup time of 2.5 s, allowing for efficient duty cycling.
