Abstract
An energy-ef ficient 920 MHz FSK transceiver for
wireless body sensor network (BSN) applications is implemented
in 0.18
m CMOS technology with 0.7 V supply. A tran sceiver
architecture based on injection-locked frequency divider (ILFD)
is proposed for the low energy consumption. In the receiver,
the ILFD in the signal path converts the recei ved FSK signal to
amplitude-modulated signal which is applied to the next envelope
detector. In the transmitter, th e ILFD is used as digitally-con-
trolled
