Abstract

A radio frequency receiver (10) comprising a mixer circuitry (11) to down-convert a received signal, which is transported on a signal line (41, 43), to baseband signal components is provided. The mixer circuitry (11) comprises a plurality of switched capacitors (CR1-CR8), each connected to the signal line (41, 43) through a signal side node (451-458) and to a corresponding switch (M1-M4) through a switch side node (471-478). In this context, a voltage is sensed at each switch side node (471-478) of the plurality of switched capacitors (CR1-CR8) and is read out through a respective grounded capacitor (CB1-CB4).
