Electromigration due to insufficient wire width can cause the premature failure of a circuit. The ongoing reduction of circuit feature sizes has aggravated the problem over the last couple of years, especially with analog circuits. It is therefore an important reliability issue to consider current densities already in the physical design stage. We present a new methodology capable of routing an...

2D nanoelectronics based on single-layer MoS2 offers great advantages for both conventional and ubiquitous applications. This paper discusses the large-scale CVD growth of single-layer MoS2 and fabrication of devices and circuits for the first time. Both digital and analog circuits are fabricated to demonstrate its capability for mixed-signal applications.

This paper describes an original methodology for accurately modeling MOSFET process parameter variations. As compared to other process parameter variation modeling methods, the proposed methodology is capable of correctly modeling not only differences of process/model parameters, but also the process parameter variations for individual devices. This capability is very important for popular anal...

Fault diagnosis of analog circuits is essential for analog and mixed-signal systems testing and maintenance. A new method is proposed in this paper for multiple fault diagnosis of linear analog circuits in frequency domain. Woodbury formula is applied to the modified nodal equation to construct the fault diagnosis equation, which relates the limited measured circuit responses with the multiple ...

Section 1: Introduction Analog technology is very important in commercial and industrial instruments and systems – such as measuring instruments and automatic control systems -that have analog inputs and outputs. Consumer equipment drives demand for improvements in analog circuit performance, and this naturally leads to performance improvements in commercial and industrial equipment. Fig.1 show...

Analog electronic circuits are an integral part of many industrial systems. Failure in such analog circuits during field operation can have severe economic implications. The presence of an expert system that can provide advance warnings on circuit failures can minimize the downtime and improve the reliability of electrical systems. Through successive refinement of circuit’s response to a sweep ...

The tradition of implementing analogue circuits by means of voltage amplifiers is almost as old as the concept of electronic circuit design. The integrated electronic circuit, however, is a relatively new concept. Furthermore, integrated electronic circuits have significantly different limitations and strengths to the conventional discrete electronic circuits have. Since the active devices in i...

In this paper we present a methodology for model-based diagnosis of analog circuits using the constraint logic programming approach. Presented methodology stems from our earlier work on the diagnosis of active analog lters by the artiicial intelligence tool CLP(<) and has the following major improvements: modeling of the diagnosed circuit is generalized to arbitrary analog circuits consisting o...
