Electromagnetic (EM) simulation has become commonplace for radio-frequency (RF) and microwave circuit designers. Interconnect discontinuities, for example, board-module-chip transitions, high-speed interconnect design, and circuit performance with compacted layout, all rely on EM simulators giving answers to predict the performance more accurately than traditional models. This article examines current trends with regard to how designers use EM tools in circuit simulators. The conclusion is that traditional stand-alone tools are disappearing. This does not mean that EM will not be used; rather, EM will be so highly integrated into the design software that much of it will be hidden from the average designer. © 2000-2012 IEEE.

IBM's Electronic Circuit Analysis Program (ECAP) analyzes linear circuits described by LCR components and by controlled and independent sources. On the other hand, COMPACT displays a remarkable combination of simplicity and important features. COMPACT used a cascade formulation, in which each circuit element was treated as a two-port block that could be cascaded with other blocks or connected in series or parallel. While SPICE has major limitations for use with microwave circuits, it was still used to some degree for microwave design. Harmonica/Spectre used SPICE models and an advanced sparse-matrix solver that was similar to the one in SPICE3. Object-oriented design simplifies the design and maintenance of complex software systems, allowing greater versatility, as objects can be used in a multiplicity of ways.

The evolution of technologies is affected not only by direct technical needs but also by historical precedents. The direction of any technology is thus affected as much by Its history as its science. In this paper, we examine how historical precedents in circuit simulation technology have, and will, motivate its future development. © 2010 IEEE.

IEEE Transactions on Terahertz Science and Technology | Year: 2012

The successful engineering of sources and components in the terahertz (THz) regime benefits from good characterization of materials properties. Previous research reports have shown that calculations of material parameters that are valid at radio frequencies are no longer accurate at THz frequencies. A high-quality-factor quasi-optical hemispherical resonator operating between 300 GHz-1 THz has been designed and implemented for the measurement of electronic properties of conductors as well as low-loss dielectrics. This apparatus is the first quasi-optical resonator to achieve Q ≈ 4 × 10 5 at frequencies greater than 400 GHz in the THz regime. It is also the first open resonator designed to measure effective conductivity at these frequencies. This paper discusses the techniques that enabled high-Q operation in the THz regime. It also includes measurements of silicon with different doping densities and conductors of various surface roughness values with comparison to theoretical predictions. © 2012 IEEE.

It is difficult to pinpoint the invention of the mixer. Although the superheterodyne receiver was invented by Edwin Howard Armstrong around 1918, the use of heterodyne techniques began much earlier, and a crude modulator, arguably a sort of mixer, existed in 1906. Thus, we are currently at a soft 100-year anniversary of the mixer, so it seems like a good time to look back at that technology to see how it arose. It's a good story. © 2000-2012 IEEE.

A system and method for automatically modifying a first layout of a circuit. The first layout may describe a plurality of layers used in a fabrication process to manufacture the circuit. When performed, the fabrication process may result in a vertical electrical connection between two of the layers. However, the vertical electrical connection may not be directly specified by the first layout. The system and method may operate to apply a set of rules to the first layout to automatically generate a modified layout directly specifying a vertical electrical connection between the two layers. The set of rules may be based on knowledge of the fabrication process, and may be designed to modify the geometry of the first layout to more closely model the real geometry of the circuit that will result from the fabrication process. The modified layout may enable an electromagnetic (EM) simulation of the circuit to be accurately performed.

Automatically modifying a layout to perform circuit simulation. Initially, a first layout of the electronic system may be received or stored. A second layout of the electronic system may be automatically generated based on the first layout. The automatic generation may involve automatically simplifying the first layout using a set of rules for electromagnetic (EM) simulation. The second layout may then be used to perform EM simulation of the electronic system, e.g., to perform verification.

A vendor agnostic, nonlinear behavioral model that accurately accounts for all of a device's nonlinear effects and works with a variety of RF and microwave simulators is very valuable to designers. First, simulation tool support is very important. With all the model choices, designers need to be able to choose the model with the best availability and capability and know that their design tools will support it. Compact models, although complex to create and not always formulated to maximize performance in a simulator, are very much the dominant model for circuit-level simulation. Even for component-level simulation blocks, the lack of model fidelity when co-simulated with a system simulator presents an issue to designers trying to work with modulated signals or analyze system-level impairments. There are several system-level models that offer more model fidelity in a system-level simulator than using circuit- level behavioral models in a system-level simulator.
