Abstract:
1. A receiver, comprising: an amplification module coupled to receive a radio frequency (RF) signal to produce an amplified RF signal; a mixer module that produces a down converted signal based on the amplified RF signal; a filter module that produces a filtered signal based on the down converted signal; an analog-to-digital (A/D) converter module that produces a digital bit stream based on the filtered signal; a processing module coupled to receive and process the digital bit stream; logic circuitry coupled to power down and then power up at least a portion of one of the amplification module, the mixer module, the filter module, the A/D converter module, and the processing module; and a bias filtering module coupled to at least one of the amplification module, the mixer module, the filter module, the A/D converter module and the processing module to provide therefor one of a plurality of filtered bias levels, wherein the bias filtering module provides filtering for an initial bias level, relative to a trigger event, for enabling fast power up and further provides a final filtered bias level with improved filtering.
