Book Description

All interconnecting wires should be considered as transmission lines in very high speed circuitry. Consideration is given to two groups of methods which are used in the design of very high speed tunnel diode switching and logic circuits. In the first method it is assumed that all constants are ideal lumped constants and that they are interconnected ideally at first. They are then replaced by distributed circuitry. In the second method tunnel diodes are connected to distributed circuitry from the beginning. In the latter method it may be possible to discover the circuitry in which the characteristic of the distributed circuit is used in our favor. It is impossible to derive this type of circuit from the lumped constant circuit. The character of the tunnel diode circuits coupled into distributed circuits is not understood well enough to design very high speed switching and logic circuits. In this report, typical tunnel diode circuits coupled into transmission lines are investigated as the preparatory stage of latter design methods. Amplifiers, oscillators and switching circuits are considered. (Author).
