An adaptive band-pass filter for a wireless receiver comprises a band-pass filter associated with the receiver, the band-pass filter configured to selectively filter the received signal, and a switch responsive to a control signal, the switch configured to control the band-pass filter based on a level of the received signal.

System for adaptively filtering a received signal in a wireless receiver

A low-noise switching voltage regulator for supplying a voltage to a radio frequency (RF) power amplifier is disclosed. In one embodiment, the invention can be conceptualized as a power amplifier supply circuit, comprising a pair of oppositely polarized semiconductor switches, and a data formatter configured to supply a data stream having a voltage transition on at least every other bit to each of the pair of oppositely polarized semiconductor switches.

Low noise switching voltage regulator

A power control loop for a power amplifier is disclosed. Embodiments of the power control loop include deriving a secondary control signal. The secondary control signal may be used to control a gain applied to the power signal in the power control loop and to control a supply current or voltage delivered to a power amplifier.
