Abstract:
A circuitry arrangement (1) comprising several electronic parts (25, 26) mounted to a circuit board (2), at least one conductor section (4, 5) extending between the electronic parts (25, 26) within a first conductor layer, and a closed conductor loop (13) comprising at least one loop section (6, 7) running in parallel to the at least one conductor section (4, 5) within a second conductor layer neighboring the first conductor layer. The closed conductor loop (13) is configured to reduce a tendency towards oscillations of a current flowing through the conductor section (4, 5) in operation of the circuitry arrangement (1). The conductor loop (13) is closed via at least one electronic component (11) mounted to an outer surface (3) of the circuit board (2).
Abstract:
A capacitor mounting structure for printed circuit boards wherein the capacitor includes first and second terminals (15a,15b) which are connected to first and second conductor planes (44,45) in the printed circuit board (B). Three vias (41,42,43) are mounted in the printed circuit board (B) in a position to be aligned with the middle of the capacitor. A first conductor pad (45) is mounted underneath one end of the capacitor and includes spaced apart extension portions (45b,45c) which electrically attach to the first (41) and third via (43). A second conductor pad (44) is mounted under the other end of the capacitor and includes a central extension portion (44b) which attaches to the second or middle via (42). In this manner, the region available for generation of parasitic inductance is minimized thereby increasing the operating efficiency of the capacitor.

Abstract:
A photodetector module that can achieve impedance matching and power saving. A photodetector (11) and an amplifier (12) for amplifying an electric signal from the photodetector (11) are mounted on a stem (14). A dielectric plate (18) is arranged between the stem (14) and a flexible substrate (20). To transfer an electric signal from the amplifier (12) to the substrate (20), a lead pin (15d) is provided to pass through the stem (14) and the dielectric plate (18). The output of the amplifier (12) includes a capacitance component, and the output impedance of the amplifier (12) is higher than the impedance that matches with the substrate (20). Further, the thickness d of the dielectric plate (18) is such that the inductance component of the lead pin (15d) includes an inductance component that is inductive, which cancels the capacitance component of the amplifier, and impedance matching with the substrate (20) can be achieved.
