| 20110053541 | DYNAMIC RANGE ON-DEMAND FOR RECEIVER APPLICATIONS - Receiver power techniques are disclosed that allow for real-time adjustment of receiver dynamic range by virtue of supplied DC power, based on signal strengths currently received by the receiver. The disclosed techniques use real-time monitoring of receiver output to detect the presence of large signals, and to then adjust bias points in the receiver to reduce DC power consumption in the absence of large signals. By adapting the power to the current signal environment by autonomously adjusting the bias points, the mean power consumption of the receiver can be greatly reduced. This in turn has a number of benefits, such as increased battery life, decreased heat, increased circuit lifetime, and decreased noise figure. | 03-03-2011 |
