A 400 /spl mu/W-RX, 1.6mW-TX super-regenerative transceiver for wireless sensor networks

A fully integrated 2GHz super-regenerative transceiver is implemented in a 0.13 /spl mu/m CMOS process. The transmit and receive paths utilize BAW resonators, yielding a 450 /spl mu/W 1V RF front-end and a transmitter delivering 380 /spl mu/W with 23% efficiency. At 5kb/s, the receiver achieves a sensitivity of -100.5dBm for 10/sup -3/ BER.
