Abstract
Systems, methods, and articles of manufacture, including computer program products, are provided for capacitive passive mixer baseband receivers with broadband harmonic rejection. In some embodiments, an apparatus is provided. The apparatus includes a receiver configured to receive an input signal and generate, based on the input signal, an in-phase portion and a quadrature phase portion. The apparatus further includes a harmonic rejection mixer comprising a plurality of capacitors, the plurality of capacitors encoded with a plurality of capacitance values, the harmonic rejection mixer configured to reduce harmonics in the input signal based on applying a quantity of the plurality of capacitance values to the input signal. The apparatus further includes a plurality of switches configured to activate the plurality of capacitors, the quantity of the plurality of predetermined capacitance values applied to the input signal based on a quantity of the plurality of capacitors that are active.
