The worldwide diffusion of wireless telecommunication systems opened new perspectives for microwave technologies. High-volume microwave monolithic integrated circuit (MMIC) production became a reality, revolutionizing the approach to microwave-circuit design. Nowadays, this is based on the intensive use of accurate simulation and computer-aided-design (CAD) tools. While scattering parameter mea...

One of the hardest problems in digital circuit design is test pattern generation for a complex device. This is difficult in part because it requires reasoning about how to control a device whose behavior can be extremely complex. Knowledge of the specific operations that the device was designed to perform can help solve this problem. The key observation is that a device’s designed behavior is o...

This paper describes a study of membrane potentiometers and long force sensing resistors as tools to enable greater interaction between performers and audiences. This is accomplished through the building of a new interface called the Helio. In preparation for the Helio's construction, a variety of brands of membrane potentiometers and long force sensing resistors were analyzed for their suitabi...

Lager is an integrated CAD system for algorithmspecific IC design. It consists of a behavioral mapper and a silicon assembler. To generate a chip from a behavioral description, the user specifies both the behavioral description and a parameterized structural description. The behavioral mapper maps the behavior onto the parameterized structure to produce microcode and parameter values. The silic...

This paper analyzes the issues that face digital circuit design methodologies and tools which address energy-efficient digital circuit sizing. The best known techniques for resolving these issues are presented, along with the sources of error. The analysis demonstrates that input slope independent models for energy and delay and stage based optimization are effective for analyzing and optimizin...

A latchup current self-stop methodology and circuit design, which are used to prevent damage in the bulk CMOS integrated circuits due to latchup, are proposed in this paper. In a bulk CMOS chip, the core circuit blocks are always latchup sensitive due to a low holding voltage of the parasitic SCR path. The proposed latchup prevention methodology and circuit design can detect and stop the occurr...

The wireless communication systems design plays the important roles in the field of microelectronics and system-on-chip methodologies. Traditional digital, mixed signal and analog low-frequency designers have enjoyed an integrated front-to-back IC design system. On the other hand, radio frequency or microwave designers with a discrete design background have used board-level computer-aided desig...

For simple digital circuits, conventional method of designing circuits can easily be applied. But for complex digital circuits, the conventional method of designing circuits is not fruitfully applicable because it is time-consuming. On the contrary, Genetic Programming is used mostly for automatic program generation. The modern approach for designing Arithmetic circuits, commonly digital circui...
