摘要： Aspects of a method and system for on-demand linearity in a receiver are provided. In this regard, in a receiver such as on-chip receiver, a strength of a signal received by one or more antennas may be measured and linearity of the receiver may be controlled in response to the measured signal strength. The linearity may be controlled based on signal strength of in-band and/or out-of-band signals and by configuring component(s) of the receiver. Exemplary components may comprise one or more filter, amplifier, mixer, analog-to-digital converter, feedback loop, and equalizer and/or post corrector. Linearity may be increased, by switching one or more feedback loops and/or an equalizers and/or post correctors into a signal path of the receiver. Power consumption may be decreased, at the expense of reduced linearity, by switching one or more feedback loops and/or an equalizers and/or post correctors out of a signal path of the receiver.
