Abstract
In this paper, alternative expressions for the pole-frequency sensitivities and pole-Q sensitivities are presented for third- and fourth-order filter transfer functions. The expressions do not require a knowledge of the parasitic poles. These closed-form expressions will be useful for sensitivity optimization of active filters.
