Also, by using a novel offset architecture, as opposed to completely overlapped architecture, for the differential transmission pair, a 33% reduction of thickness is achieved in the design of a miniaturized common-mode filter with multi-layer LTCC technology. In view of increasing need of high-speed clock and data circuits to control their skew problems, a design of LTCC delay line is then conducted. To improve the waveform distortion associated with the microstrip/stripline-type meander delay line, a miniaturized high-frequency 3-D delay line with grounded guard traces is introduced. By means of 3-D structure, the 233 ps delay time, which requires extra board space amounting to a factor of 2.34 by stripline type meander delay line, can be shrunk into an EIA 1206 form factor.
