Abstract
Apparatus having corresponding methods and non-transitory computer-readable media comprise an amplifier configured to amplify signals according to a bias current, wherein the signals represent packets of data; a packet module configured to recover the packets of data from the signals amplified by the amplifier; and a control module configured to control the bias current according to one or more characteristics of the packets of data.
Claims18
An apparatus comprising:
- an amplifier configured to amplify signals according to a bias current, wherein the signals represent packets of data, and wherein the amplifier includes a plurality of cascaded stages;
- a packet module configured to recover the packets of data from the signals amplified by the amplifier;
- and
- a control module configured to control the bias current by which the amplifier amplifies the signals, wherein the control module controls the bias current according to a signal-to-noise ratio (SNR), a received signal strength indication (RSSI), and a modulation type of each of the packets of data.
A method comprising:
- amplifying, at an amplifier having a plurality of cascaded stages, signals according to a bias current supplied to the plurality of cascaded stages of the amplifier, wherein the signals represent packets of data;
- recovering the packets of data from the signals as amplified by the amplifier;
- and
- controlling the bias current supplied to the plurality of cascaded stages of the amplifier according to a signal-to-noise ratio (SNR), a received signal strength indication (RSSI), and a modulation type of each of the packets of data.
Non-transitory computer-readable media embodying instructions executable by a computer to perform a method comprising:
- controlling a bias current supplied to a plurality of cascaded stages of an amplifier, the bias current being controlled according to a signal-to-noise ratio (SNR), a received signal strength indication (RSSI), and a modulation type of each of a plurality of packets of data,
- wherein the packets of data are recovered from signals, amplified according to the bias current supplied to the plurality of cascaded stages of the amplifier.
