On-Demand Signal Notching in a Receiver

Abstract

Aspects of a method and system for on-demand signal notching in a receiver. In this regard, signal strength measurements of a received signal may enable detection of unwanted signal component(s) and one or more filters in an on-chip receiver may be configured in response to the measurements. The filter(s) may additionally be configured based on power consumption of the filter(s). Signal measurements and/or the corresponding configuration may be performed real-time. The filter(s) may be configured such that a notch in a frequency response of the filter(s) is centered at or near the unwanted component. In this manner, the unwanted component(s) may be filtered out. The filter(s) may be configured, for example, by switching one or more filter stages and/or components into and/or out of a signal path and/or by tuning one or more variable circuit elements within the filter(s).
