Disclosed herein are techniques related to a discrete-time harmonic rejection mixer. The discrete-time harmonic rejection mixer includes a switched-capacitor network and a switch controller. The switched-capacitor network includes first, second, and third switched capacitor sub-circuits, each including a pair of capacitors and a set of switches. The switch controller is coupled to the switched-capacitor network, and is configured to operate the sets of switches. More specifically, the switch controller is configured to operate the sets of switches in an out of phase manner to produce the harmonic rejection effect. Capacitance values for the first pair of capacitors are roughly equal to capacitance values for the third pair of capacitors. An input device, method, and harmonic rejection circuit exhibiting the above features are provided as examples.
