要約(英語): It is well known that doubly terminated LC filters are low sensitive to element value deviation in the passband. This property has been expanded to passive complex filters, however, only the case for tracking deviation between real and imaginary part elements has proved. Although numerical calculation methods for arbitrary deviations have proposed, there is no mathematical analysis on mismatch error. In this paper, a preliminary study for passive complex filter sensitivity to mismatch errors between real and imaginary pair elements is given. At first, we show that any mismatch error can be decomposed into tracking and differential errors and that the latter is the subject to be analyzed. Then, we consider a passive complex filter as a multi-port output real filter and analyze its sensitivity in passband.
