A 17-mW 0.66-mm² Direct-Conversion Receiver for 1-Mb/s Cable Replacement.

A very-low-cost wireless personal area network (WPAN) receiver implemented in 0.25-µm CMOS technology consumes 17mW of power and occupies an area of 0.66 mm². Simplicity in the physical layer, which still supports the 1-Mb/s requirement, allows for power savings in the receive front-end. A new coding scheme permits the integration of a high-pass filter to mitigate DC offset and 1/f noise. A linear front-end eliminates the external band-preselect filter. This die area is the smallest reported for Bluetooth-class front-ends. [ABSTRACT FROM AUTHOR]
