Abstract: A discrete-time filter for filtering an input signal comprises a switched capacitor network, the switched capacitor network comprising an input and an output, a number of switched capacitor paths arranged in parallel between the input and the output, each switched capacitor path comprising a capacitor, and a switch circuitry for switching each capacitor at a different time instant for outputting a filtered input signal.
