Abstract
In at least one embodiment, a method for operating a receiver includes configuring a receiver front-end circuit of the receiver according to a selected power consumption configuration. The method includes adjusting a quiescent current of a programmable flat gain stage coupled to the receiver front-end circuit according to the selected power consumption configuration to compensate for any gain loss of the receiver front-end circuit in the selected power consumption configuration. The selected power consumption configuration may be a reduced power consumption configuration and the programmable flat gain stage may be configured to at least partially compensate for the gain loss of the receiver front-end circuit in the reduced power consumption configuration.
Claims18
A method for operating a receiver, the method comprising:
- configuring a receiver front-end circuit of the receiver according to a selected power consumption configuration;
- and
- adjusting a quiescent current of a programmable flat gain stage coupled to the receiver front-end circuit according to the selected power consumption configuration to compensate for any gain loss of the receiver front-end circuit in the selected power consumption configuration, the selected power consumption configuration being a reduced power consumption configuration and the programmable flat gain stage being configured to at least partially compensate for the gain loss of the receiver front-end circuit in the reduced power consumption configuration.
A receiver comprising:
- a receiver front-end circuit configured according to a selected power consumption configuration;
- and
- a variable peaking gain stage including a programmable flat gain stage and a peaking gain stage, the programmable flat gain stage being configured to have a gain according to the selected power consumption configuration and the peaking gain stage being configured according to the selected power consumption configuration, the selected power consumption configuration being a reduced power consumption configuration and the programmable flat gain stage being configured to at least partially compensate for a gain loss of the receiver front-end circuit in the reduced power consumption configuration.
A receiver comprising:
- means for configuring a receiver front-end circuit of the receiver according to a selected power consumption configuration;
- and
- means for compensating for gain loss of the receiver front-end circuit in response to the selected power consumption configuration being a reduced power consumption configuration, the means for compensating including a programmable flat gain stage configured to at least partially compensate for the gain loss of the receiver front-end circuit in the reduced power consumption configuration.
