“UNIVER”-A Fast, Versatile Multilogic Digital Amplifier for Micrologic circuits

The nature of integrated circuit fabrication limits the number of circuit modules in a system due to the high developmental cost involved. This paper describes a unique approach to designing an ultra-high speed multiple-function logic amplifier in integrated circuit form. Using the scheme of a pair of tunnel-diode coupled emitter followers driven by an emitter-coupled amplifier, it is shown that the circuit, designated UNIVER, has a capability of both storage (flip-flop) and wave-shaping functions, and can drive low impedance (35 ohms) transmission lines with a high (8) logic gain under 1 nsec total stage delay, while suppressing the oscillatory ringing commonly occurring in an emitter follower. A large number of the UNIVER circuits were built in integrated circuit form and then evaluated as multiple functional modules in a 100-Mc digital system. The logical performance and switching characteristics of the circuits were ascertained. Test results collected over a twelve-month period are discussed as well as the extended applications of the UNIVER circuit scheme. © 1964, IEEE. All rights reserved.

SLOT-LINE FILTERS AND COUPLERS

The slot-transmission line on a dielectric substrate has many possible microwave circuit applications. This paper presents experimental data concerning the performance of bandpass and bandstop filters and a hybrid coupler; the work described was performed at S-band frequencies using the single substrate slot line geometry. Also included are theoretical data concerning the slot-line wavelength and characteristic impedance for the case of the slot-line configuration having dielectric material above and below the metsllization, the so-called slot-line "sandwich."

TRANSMISSION LINE PULSE TRANSFORMERS - THEORY AND APPLICATIONS

引用

PROCEEDINGS OF THE INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS 1968年第1期56卷 47-&页

作者： MATICK, RE Thomas J. Watson Research Center IBM Corporation Yorktown Heights NY USA

The advent of fast rise-time pulse techniques and their increasing importance brought on by high-speed microminiature circuits and the computer industry has resulted in an increased demand for pulse transformers of various types. The basic idea of constructing transmission line type transformers has been known and used for a number of years. However, such devices have not gained widespread usage, partly because their existence is not well known, but largely because of a lack of basic understanding of their operating principles in terms of elementary fundamentals as well as their capabilities and limitations. The purpose of this paper is twofold. One aim is to develop in step-by-step fashion the basic ideas of transmission line transformers from ordinary transmission line theory. The subject will be approached from the point of view of pulse response rather than ac excitation as is usually the case. Both impedance transformers and balanced-to-unbalanced (balun) transformers, including inverters, will be considered with physical insights into their operation. Several fundamental concepts will be developed and explored in detail (without mathematics), since they have a strong bearing on practical applications. The second purpose is to present new information and pulse measurements which will be useful in the design and applications of such devices, showing their capabilities and hitherto unexplored limitations, as derived from the fundamental concepts. Thus, this paper is partly supplementary to other published work and partly new work with the goal of providing a convenient fundamental understanding of these devices and their inherent potential and shortcomings. Although the intention is not to give a detailed design procedure, some approximate calculations and discussion of significant design criteria are included.

The Double-Kelvin Transmission Line and Some Applications

引用

IEEE Transactions on Circuit Theory 1964年第3期11卷 372-377页

The double-Kelvin transmission line is formed when two layers of dielectric and two layers of resistive material of uniform width and thickness are placed on top of a conductive layer. The open-circuit impedance function and voltage transfer function for the two-port formed by this device are derived. The conditions for real-frequency zeros in the transfer function are developed and a locus of line parameters yielding lines with real-frequency zeros is given. The general case for the transfer function of the double-Kelvin twoport when connected in series with a linear and passive impedance is considered. Experimental verification of the analytical results are shown for three physical realizations of the double line using lumped-element circuits, thin-film circuits and parallel-plate circuits. © 1964, IEEE.

distributed AMPLIFICATION

This paper presents a new principle in wide-band amplifier design. It is shown that, by an appropriate distribution of ordinary electron tubes along artificial transmission lines, it is possible to obtain amplification over much greater bandwidths than would be possible with ordinary circuits. The ordinary concept of "maximum bandwidth-gain product" does not apply to this distributed amplifier. The high-frequency limit of the distributed amplifier appears to be determined by the grid-loading effects. The distributed amplifier provides means for designing amplifiers either of the low-pass or band-pass types. The low-pass amplifiers can be made to have a uniform frequency response from dc to frequencies as high as several hundred Mc using commercially available tubes. The general design considerations included in this paper are: The effect of improper termination of transmission lines; methods for controlling the frequency response and phase characteristic; the design which provides the required gain with fewest possible number of tubes; and a discussion of high-frequency limitations. The noise factor of the amplifier is evaluated. Practical amplifiers, designed according to the principles described in this paper, have been built and have verified the theoretical predictions. Experimental work will be described in a forthcoming paper.

Design of the First 500-kV Substations on the Southern California Edison Company System

引用

IEEE Transactions on Power Apparatus and Systems 1967年第5期PAS-86卷 531-539页

作者： Dolan, Paul R. Peat, A.J. Southern California Edison Company Los Angeles Calif. United States

The design of two new 500-kV substations has been completed and is discussed in this paper. The discussion of the design covers first a description of the 500-kV grid of transmission lines and substations that will serve as a support for the existing 220-kV system. Following the description of the new system is a discussion of the substation design criteria. The areas covered are insulation coordination, line and bus arrangement, bus conductor selection, and equipment requirements. The paper concludes with a description of the stations.
