Abstract
We present an ultra-wideband transceiver designed
for ultra-low-power communication at sub-10 cm range. The
transceiver operates at a 5.6 G Hz carrier frequency, chosen to

antenna, and can switch
its architecture between self-synchronous recti fication and low-IF
to adapt its power consumption to the channel characteristic in
real time. A low-power digital circuit exploits redundancy in the
modulation scheme to provide a real-time BER estimate us
