Adaptive analog IF signal processor for a wide-band CMOS wireless receiver
An IF strip for a wireless receiver supports a variable baud rate by changing analog filter bandwidth. Sliding and step adaptive dynamic range are both used at IF to dissipate only the necessary power at prevailing channel conditions. A combination of VGA and PGA is developed for 64-QAM. The total s...

| description | An IF strip for a wireless receiver supports a variable baud rate by changing analog filter bandwidth. Sliding and step adaptive dynamic range are both used at IF to dissipate only the necessary power at prevailing channel conditions. A combination of VGA and PGA is developed for 64-QAM. The total signal processor draws an average of 16 mA from 3.3 V and a peak of 73 mA. The differential input noise is as low as 3.9 nV//spl radic/Hz, while maximum IIP3 is +22 dBm with respect to 100 ohms. |
