Abstract
Methods for operating amplifiers and related devices. In some embodiments, a method for amplifying a signal can include partially amplifying a signal with a common amplification stage. The method can further include providing a bias signal to a selected one of a plurality of dedicated amplification stages each coupled to the common amplification stage and including an output node, such that the selected dedicated amplification stage further amplifies the partially amplified signal and provides the further amplified signal at the respective output node.
Claims17
A method for operating an amplifier, the method comprising:
- partially amplifying a signal with a common amplification stage;
- providing a bias signal to a selected one of a plurality of dedicated amplification stages each implemented between the common amplification stage and a respective output node, such that the selected dedicated amplification stage further amplifies the partially amplified signal, the providing of the bias signal including routing of the bias signal through a pole of a switch, a throw of the switch, and the selected dedicated amplification stage corresponding to the throw of the switch;
- and
- routing the further amplified signal from the selected dedicated amplification stage to the respective output node through a dedicated harmonic trap.
A method for operating an amplifier, the method comprising:
- partially amplifying a signal with a common amplification stage;
- providing a bias signal to a selected one of a plurality of dedicated amplification stages each dedicated amplification stage coupled to the common amplification stage without any switch, and also coupled to a respective output node, such that the selected dedicated amplification stage is enabled and further amplifies the partially amplified signal;
- and
- routing the further amplified signal from the selected dedicated amplification stage to the respective output node through a dedicated harmonic trap.
A method for processing a signal, the method comprising:
- partially amplifying an input signal with a common amplification stage;
- further amplifying the partially amplified signal with a selected one of a plurality of dedicated amplification stages each dedicated amplification stage coupled to the common amplification stage without any switch and also coupled to a respective output node, the further amplifying including selectively providing a bias signal to enable the selected dedicated amplification stage;
- and
- routing the further amplified signal from the selected dedicated amplification stage to the respective output node through a dedicated harmonic trap.
A method for operating a wireless device, the method comprising:
- generating or providing a signal;
- amplifying the signal, the amplifying including partially amplifying the signal with a common amplification stage, and further amplifying the partially amplified signal with a selected one of a plurality of dedicated amplification stages each dedicated amplification stage coupled to the common amplification stage without any switch and also coupled to a respective output node, the further amplifying including selectively providing a bias signal to enable the selected dedicated amplification stage;
- and
- routing the further amplified signal from the selected dedicated amplification stage to the respective output node through a dedicated harmonic trap.
