Abstract:
1. A charge domain filter, comprising: a phase divider, receiving a first input signal and a second input signal, to generate a plurality of first phase divided signals according to the first input signal and to generate a plurality of second phase divided signals according to the second input signal; a plurality of first switched capacitor networks, holding a one to one relationship with the first phase divided signals, wherein each of the first switched capacitor network has an input terminal receiving the corresponding first phase divided signal and has an output terminal; a plurality of second switched capacitor networks, holding a one to one relationship with the second phase divided signals, wherein each of the second switched capacitor network has an input terminal receiving the corresponding second phase divided signal and has an output terminal; a connecting circuit, forming connections between the output terminals of the first and second switched capacitor networks to generate a plurality of output signals.
