| Abstract: | In this paper a new concept of non-drift active filter is proposed. The principle,clrcuit structure,design formulas and experiment results of n-th-order non-drift all-pole active low-pass filters are Introduced in detail. The filter has not DC drift at all. It features simplicity in structure,easiness for design and fine performance,suitable for obtaining high-sensitivity and low DC drift in high--precision measuring systems. |

| Keywords: | Direct current drift Active filter Low-pass filter Non-drift active low-pass filter |
