    Abstract: A mixer, a receiver, and a method provide dynamic sub-sampling mixer which adjust a sub-sampling rate based on power drain and performance. A mixer includes mixer circuitry receiving an input of a Radio Frequency (RF) input signal and providing an output of a baseband signal of the RF input sampled at a sub-sampling rate, baseband parametric control circuitry receiving the baseband signal and measuring at least one parametric value of the baseband signal, and sampling period control circuitry receiving the at least one parametric value and adjusting the sub-sampling rate based thereon, the sub-sampling rate or ratio is adjusted minimize power drain while ensuring performance of the at least one parametric value is satisfying a predetermined level.

    Abstract: Improving signal quality by sampling an intermediate frequency signal by an analog-to-digital converter (ADC) and determining spectral characteristic data of the output signal of the ADC, and processing the spectral characteristic data to identify blocking signals and blocking spur signals that interfere with any desired signals. An adjustment is made to the frequency of one or more oscillators to reduce the interference resulting from the blocking signals if a ratio of the desired signal level to the total interfering blocker spur level is below a threshold.
