1. A radio frequency receiver comprising:
a mixer circuitry to down-convert a received signal that is transported on a signal line to baseband signal components, wherein the mixer circuitry is arranged in a bottom plate configuration and further comprises:
a plurality of switched capacitors, each of the plurality of switched capacitors is driven according to a respective clock phase and is connected to the signal line through a signal side node; and
a switch side node connecting a corresponding switch to the signal side node such that a voltage detected at each switch side node of the plurality of switched capacitors and is read out through a respective grounded capacitor driven according to a second clock phase, wherein the second clock phase is different than the clock phase.
