Abstract
An electronic module designed for maximum switching speeds is described. It contains parallel strip conductors having spacings much smaller than their widths and serving as two-dimensional outgoing line and two-dimensional return line of the direct-current supply. The strip conductors are bridged by one or more additional capacitors, particular spacings being provided between the individual additional capacitors and between such additional capacitors and the edge of the strip conductors.
Claims13
An electronic module of flat construction having a plurality of parallel strip conductors with spacing between said strip conductors being less than the width of those conductorrs, at least a pair of said strip conductors having terminals at ends thereof for connection to a source of current and being constructed to form two dimensional outgoing and incoming lines for a current supply to operating components mounted on said module comprising:
- a plurality of adjacent first capacitors connected between said outgoing and incoming lines and
- low pass filter means formed by pairs of said adjacent first capacitors and the segments of said incoming and outgoing lines lying between said pairs of first capacitors and formed by those of said first capacitors lying closest to any edge points of said strip conductors and segments of said incoming and outgoing lines lying between said edge points and said first capacitors lying closest to said edge points,
- said adjacent first capacitors being spaced one from the other and the distance from edge points of said incoming and outgoing lines to said first capacitors, respectively, lying closest to said edge points being sufficiently small as to form a said low pass filter means having a greater cut off frequency than the highest frequency component of interfering voltages occurring on said incoming and outgoing lines upon operating electronic components connected to said current supply.
An electronic module having parallel strip conductors and a pair of said strip conductors forming two dimensional incoming and outgoing lines for current supply, the spacing between said parallel strip conductors being smaller than the widths of said incoming and outgoing lines, comprising:
- a plurality of terminals for making connections to components on said module and
- a plurality of shunt capacitors connected between pairs of said strip conductors, said connection being made in portions of said module adjacent said terminals, said shunt capacitors having internal resistance values matched to the characteristic impedance of said strip conductors.
An electronic module of flat construction having a plurality of parallel strip conductors with spacing between said strip conductors being less than the width of those conductors, at least a pair of said strip conductors having terminals at ends thereof for connection to a source of current and being constructed to form two-dimensional outgoing and incoming lines for a current supply to operating components mounted on said module, comprising:
- a first capacitor connected between said outgoing and incoming lines and
- low pass filter means formed by said first capacitor and segments of said incoming and outgoing lines extending between those edge points of said incoming and outgoing lines closest to said first capacitor and said first capacitor,
- the distance between said first capacitor and said edge points being sufficiently small as to form said low pass filter means to have a greater cut off frequency than the highest frequency component of interfering voltages occurring on said incoming and outgoing lines upon operating electronic components connected to said current supply.
