Abstract
The present invention provides for operation of a digital communication receiver having multiple operational modes so that power consumption of the system can be kept at a minimum by using the lowest power operation for the system components performing tasks associated with each of the respective one of the multiple operational modes. An example is the receiver A/D converter operation with the lowest power to provide the desired resolution. Also, the invention provides novel architectures for implementing scalable resolution A/D converters. Furthermore, the invention generally includes a novel architecture for controlling the dynamic range of an A/D converter. In addition, the invention generally involves novel architectures for controlling the dynamic range of an A/D converter to alleviate difficulties associated with AGC control loops. Multiple exemplary embodiments are disclosed.
