Abstract :
A 2.4GHz radio for IEEE 802.15.4 WPANs using 0.18/spl mu/m CMOS technology consumes 21mW and 30mW at 1.8V supply in RX and TX mode, respectively. The receiver utilizes a low-IF architecture with a poly-phase filter and transistor linearization technique. A ROM-based DSSS GMSK signal is directly up-converted using I/O mixing. Silicon area is 8.75mm/sup 2/.
