Abstract :
A Bluetooth radio in 0.18 /spl mu/m CMOS technology works on 2.5-3.0 V, dissipating 75 mW in RX and 90 mW in TX. RX uses a 2 MHz IF with an active poly-phase bandpass filter. The fractional-N PLL uses a VCO running at 5 GHz. TX uses IQ modulation. Special attention is paid to Si-crosstalk because this radio is combined with baseband circuitry. Silicon area is 5.5 mm/sup 2/.
