Abstract:
A system and method for “pixelating” a three-dimensional circuit structure into a three-dimensional matrix of cubes that are located with respect to a coordinate system. The design step is typically performed on a conventional computer using computer aided design software that pixelates the proposed circuit structure into an array of uniformly sized cube. The fabrication process involves adding and subtracting bulk materials from the individual cubic positions within the pixelated representation of the circuit structure. Various existing and new techniques can be used to add or subtract bulk materials as the cubic positions within the matrix to construct the circuit structure.

Abstract:
A filter circuit 103 includes capacitor elements 121 and 122. The capacitor element 121 returns a common mode current included in a signal output from, a signal output terminal 111 of a semiconductor element 102, to a ground terminal 113 of the semiconductor element 102. The capacitor element 122 returns a common mode current included in a signal output from a signal output terminal 112 of the semiconductor element 102, to the ground terminal 113 of the Semiconductor element 102. The capacitor elements 121 and 122 are arranged such that the mutual inductance between a parasitic inductance of the capacitor element 121 and a parasitic inductance of the capacitor element 122 for the common mode currents is a negative value. Accordingly, the effective inductances of the first and second capacitor elements for the common mode currents are reduced, which suppresses radiation noise.
