    摘要： A mixer-first receiver operates to generate filtering and analog-to-digital conversion concurrently and adaptively, while removing an LNA before a mixer to enable integration with digital baseband circuits. A plurality of switching capacitor arrays are integrated with a hybrid analog-to-digital filtering component. Switching capacitor arrays of the plurality of switching capacitor arrays can be selectively modified to perform both the filtering operation and the conversion operation together. The same switch capacitors of a switching capacitor array can be utilized in one phase of a clock cycle for the filtering and in another phase of the clock cycle for the conversion.

    摘要： An apparatus is provided which comprises: a mixer to mix a first signal of a first frequency with a second signal of a second frequency, and to generate a first output; a switched-capacitor multiplier, coupled to the mixer, to receive the first output and to provide a second output with reduced noise; and an amplifier, coupled to the switched-capacitor multiplier, to amplify the second output.
