| 摘要 |
The invention relates to a filter circuit (200), comprising at least one first filter strand (210). The first filter strand (210) comprises a first input circuit (10), a first integration circuit (20) and a first output circuit (30). The first input circuit (10) is configured to convert an input signal according to the value of the input signal into at least two distinguishable first first-stage output signals, and forward the first-stage output signals during a predetermined time period to the first integration circuit (20, 420). The first integration circuit (20) is configured to integrate the first first-stage output signals of the first input circuit (10) over the predetermined time period and generate a first integration signal (25). The first output circuit (30) is configured to compare the first integration signal (25) to a first output reference value and generate a first second-stage output signal (35). The invention, furthermore, relates to a corresponding method for filtering. |
