A charge domain filter having a phase divider, first switched capacitor networks, second switched capacitor networks and a connecting circuit. The phase divider receives a first and a second input signal to output first phase divided signals based on the first input signal and second phase divided signals based on the second input signal. The first switched capacitor networks, holding a one to one relationship with the first phase divided signals, each has an input terminal receiving the corresponding first phase divided signal and has an output terminal. The second switched capacitor networks, holding a one to one relationship with the second phase divided signals, each has an input terminal receiving the corresponding second phase divided signal and has an output terminal. The connecting circuit determines connections between the output terminals of the first and second switched capacitor networks to generate a plurality of output signals.
