A 2nd-order Lowpass Filter with Low Group-Delay Sensitivity
초록
This paper proposes a constant time-delay filter with low sensitivity, which can be used for hard-disk drive. The sensitivity of 2nd order lowpass filter by two kinds of method, one is based on lossy integrators and the other is lossy and lossless integrators is analyzed and designed. SPICE simulation shows fesibility of a filter by the proposed approach.
