Abstract
The signal interference technique is firstly employed to design the common-mode filter (CMF) for differential digital circuit applications. Using the network analysis, design curves for three common-mode transmission zeros are available by simple steps. A test sample is realized in two-layer PCB. The fractional bandwidth of common-mode suppression band (|S cc21 | dd21 |) is better than -3 dB from DC up to 10 GHz in measurement. The flat differential-mode group delay implies this CMF can preserve good signal integrity, which is obvious by eye diagram measurement in time domain.
