Method and apparatus for an energy-efficient receiver

摘要

One or more circuits may comprise at least one first-type analog-to-digital converter (ADC) and at least one second-type ADC. The circuit(s) may be operable to receive a plurality of signals, each of which may comprise a plurality of channels. The circuit(s) may be operable to digitize a selected one or more of the channels. Which, if any, of the selected channels are digitized via the at least one first-type ADC and which, if any, of the selected channels are digitized via the at least one second-type ADC, may be based on which of the plurality of channels are the selected channels and/or based on power consumption of the circuit(s). A bandwidth of each first-type ADC may be on the order of the bandwidth of one of the received signals. A bandwidth of each second-type ADC may be on the order of the bandwidth of one of the plurality of channels.

1. A system comprising:
one or more circuits comprising at least one first-type analog-to-digital converter (ADC) and at least one second-type ADC, wherein said one or more circuits are operable to:
receive a plurality of signals, each of said plurality of signals comprising a plurality of channels; anddigitize a selected one or more of said plurality of channels via said at least one first-type ADC and/or said at least one second-type ADC, wherein which, if any, of said selected one or more of said channels are digitized via said at least one first-type ADC and which, if any, of said selected one or more of said channels are digitized via said at least one second-type ADC, is based on which of said plurality of channels are said selected one or more of said channels.
