Abstract: PURPOSE:To individually adjust resonance frequencies and to obtain a stable frequency characteristic by arranging unit resonators, which are different in specific dielectric constant and are short-sized, in parallel. CONSTITUTION:A conductive layer 12 which forms an electrode together with an outer peripheral face 6 and an earth end face 3 of a dielectric block constituting respective unit resonators 1-1 to 1-3 is formed on an end face 2 of this dielectric block except parts around respective flange pins 4. A dielectric lower plate 8 interposed between a pair of elastic insulating sheets 7 is placed on the end face 2 together with respective insulating sheets 7 with apertures 9 and 10, through which flange pins 4 are inserted, between them. A dielectric upper plate 11 which has a conductive layer 12 divided correspondingly to unit resonators on the lower face and has input/output terminals on the upper face is placed on the upper insulating sheet, and they are finally fixed into one body by clamping tools. Thus, a dielectric block base material 1 constituting unit resonators has a uniform resonance length, namely, height, and the dielectric constant is arbitrarily selected in accordance with the resonance frequency.

Filed: 1990-02-07
Abstract: PURPOSE:To verify an electric characteristic even to the layout pattern of a large-scale logical circuit by using a verification data calculated based on a reference circuit constant extracted from a layout pattern data and a given process parameter. CONSTITUTION:Before the verification of the electric characteristics of a logical circuit, the logical verification of the circuit connection data itself of the logical circuit corresponding to the layout pattern is executed by a logical circuit verification part 100. In such the case, the verification data which is used by a verification data decision part 104 when judging the normal/defective condition of the electric characteristic of the logical circuit is the data calculated by a verification data calculation part 103 based on the reference circuit constant extracted by a second data extraction part 102 from a layout pattern data d2 and the process parameter given by a process parameter giving means d3, that is, a data obtained without executing a circuit simulation. Thus, even for the layout pattern of the large-scale logical circuit, its electric characteristic can be verified easily.
