Functional adjustment of thick film distribution-lumped active low-pass filters

It is shown that distributed RC networks with properties close to the ideal can be constructed by using the thick film technology. The application of the distributed RC network to construct low pass active filters is described and it is shown that miniature low pass active filters can be constructed using these networks. The construction of an eighth order Butterworth distributed low pass active filter, whose individual stage's magnitude response is adjusted by trimming the distributed RC network, is described.
