The equations which present the relations between the integrated elements of the band-pass and low pass filters for parallel and serial resonators are as follows:
If the low pass filter's transmission function [H.sub.L](s) is needed from low pass prototype H(s), then from formula (1), and based on the formula (8), to let the [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] invariable, choose the matrix elements B = [w.sub.c], [w.sub.0] = 0, and put them back to the formula, and then the result is coming.
In Figure 1, Type A & Type B are same low pass filters, and the only difference is the bias DC pads.
