Abstract
A 17 GHz low-power radio transceiver front-end im-
plemented in a 0.25
m SiGe:C BiCMOS technology is described.
Operating at data rates up to 10 Mbit/s with a reduced transceiver
turn-on time of 2
s, gives an overall energy consumption of
1.75 nJ/bit for the receiver and 1.6 nJ/bit for the transmitter. The
measured conversion gain of the receiver chain is 25–30 dB into

0.5 dB across
the band from 10 to 200 MHz. The 1-dB compression point at the
