摘要:
A computer-implemented method of generating a library object for an integrated circuit design is disclosed. In one embodiment, the method includes: analyzing a pair of integrated circuit design objects for fringe capacitance effects between the pair of integrated circuit design objects; and generating the library object accounting for the fringe capacitance effects prior to completion of a layout design for the integrated circuit design.

Coplanar waveguide structures and design structures for radiofrequency and microwave integrated circuits. The coplanar waveguide structure includes a signal conductor and ground conductors generally coplanar with the signal conductor. The signal conductor is disposed between upper and lower arrays of substantially parallel shield conductors. Conductive bridges, which are electrically isolated from the signal conductor, are located laterally between the signal conductor and each of the ground conductors. Pairs of the conductive bridges connect one of the shield conductors in the first array with one of the shield conductors in the second array to define closed loops encircling the signal line.

T-connections, methodology for designing T-connections, and compact modeling of T-connections. The T-connections include an electrically conductive T-junction comprising a body and first, second and third integral arms projecting from mutually perpendicular sides of the body, each arm of the three integral arms having a same first width abutting the body and a same length extending away from the body; an electrically conductive step-junction comprising a first section having the first width and an integral and abutting second section having a second width, the second width different from the first width, the first section smoothly abutting and integral with the first arm of the T-junction; and wherein top surfaces of the T-junction and the step-junction are coplanar.

Methods for fabricating a coplanar waveguide structure. The method may include forming first and second ground conductors and a signal conductor in a coplanar arrangement between the first and second ground conductors, forming a first coplanar array of substantially parallel shield conductors above the signal conductor and the first and second ground conductors, and forming a second coplanar array of substantially parallel shield conductors below the signal conductor and the first and second ground conductors. The method further includes forming a first plurality of conductive bridges located laterally between the signal conductor and the first ground conductor, and forming a second plurality of conductive bridges located laterally between the signal conductor and the second ground conductor. Each of the first plurality of conductive bridges connects one of the shield conductors in the first array with one of the shield conductors in the second array. Each of the second plurality of conductive bridges connects one of the shield conductors in the first array with one of the shield conductors in the second array.

The invention is a tunable RF MEMS switch developed with a BST dielectric at the contact interface. BST has a very high dielectric constant (>300) making it very appealing for RF MEMS capacitive switches. The tunable dielectric constant of BST provides a possibility of making linearly tunable MEMS capacitive switches. The capacitive tunable RF MEMS switch with a BST dielectric is disclosed showing its characterization and properties up to 40 GHz.
