DISCRETE-TIME FILTER

摘要

The invention relates to a discrete-time filter for filtering an input signal, the discrete-time filter comprising a switched capacitor network, the switched capacitor network comprising an input (102) and an output (104), a number of switched capacitor paths (101, 103, 105, 107) arranged in parallel between the input (102) and the output (104), each switched capacitor path (101, 103, 105, 107) comprising a capacitor, and a switch circuitry (121, 125, 127) for switching each capacitor at a different time instant for outputting a filtered input signal.
