Abstract:
1. Circuitry for amplifying an input signal, said circuitry comprising: a first amplification stage configured to receive said input signal and provide a first amplified output signal to a first signal detector to produce a first detector signal; a second amplification stage connected downstream of said first amplification stage and configured to provide a second amplified output signal to a second signal detector to produce a second detector signal; a third amplification stage, as part of an analog to digital converter, configured to amplify said second amplified output signal before conversion to a digitized third amplified output signal; a gain control circuit configured to receive said first and second detector signals and adjust a first gain factor of said first amplification stage and a second gain factor of said second amplification stage; a signal strength indicator module that receives the digitized third amplified output signal from the analog to digital converter and determines a received signal strength indication (RSSI) value corresponding to the digitized third amplified output signal; said gain control circuit configured to receive the digitized third amplified output signal and the RSSI value, and adjust a third gain factor of said third amplification stage based on said digitized third amplified output signal and the RSSI value; and a digital recovery module configured to adjust an in-phase sequence of data and a quadrature phase sequence of data to provide real-time adjustment of sequence parameter values, wherein said circuitry is configured to operate at multiple frequency bands.
