Abstract:
1. A wireless communication receiver, comprising: a receive path configured to receive a wireless communication signal and convert the wireless communication signal into a digital signal based at least on an oscillator signal, the receive path comprising hardware including a downconverter, an analog-to-digital converter and an equalization filter located after the analog-to-digital converter in the receive path; a control path communicatively coupled to the receive path and configured to: determine a signal strength of a signal in the receive path; based at least on the signal strength, select a current mode from at least one of a first current mode and a second current mode for the wireless communication receiver, wherein the receive path has a first receive path gain and a first receive path delay in the first current mode and has a second receive path gain and a second receive path delay in the second current mode; and communicate a control signal to the receive path indicative of the current mode; the receive path configured to: in response to the switch from the first current mode to the second current mode as indicated by the control signal, modify one or more operational parameters of the receive path such that the receive path consumes a lower amount of current than it does in the first current mode; and in response to the switch from the second current mode to the first current mode as indicated by the control signal, modify one or more operational parameters of the receive path such that the receive path consumes a higher amount of current than it does in the second current mode; and the equalization filter configured to, in response to a switch from the first current mode to the second current mode or a switch from the second current mode to the first current mode, modify a gain and a delay of the equalization filter to compensate for a gain difference between the first receive path gain associated with the first current mode and the second receive path gain associated with the second current mode, and to compensate for a delay difference between the first receive path delay associated with the first current mode and the second receive path delay associated with the second current mode.
