provide a simple electrical equivalent circuit that lends itself to circuit analysis. The magnetic structure shown in Figure 1 will be the first demonstration of this technique. This simple inductor is built upon a ferrite core, with air gaps to store the required inductive energy created by simply shimming the two core halves apart (not usually a good practice, but inexpensive). Purpose: I. To...

The paper will give an application oriented introduction into symbolic analysis of analog electronic circuits. Starting with a brief review of the problems in current industrial analog circuit design an overview of the state of the art concerning the functionality of symbolic analysis methods will be given. Special attention will be devoted to the subject of symbolic approximation strategies in...

How can cells shape and utilize dynamic gene regulation to enable complex cellular behaviors? I study this question in natural and a synthetic context. The first project studies how a natural genetic network can imbue cells with a sense of ‘time’. It has long been known that environmental signals induce diverse cellular di↵erentiation programs. In certain systems, cells defer di↵erentiation for...

This brief provides a detailed analysis of active pixel sensor, pixel and column circuit. Surprisingly, we find that shorter readout times can be achieved by reducing the bias current and hence reducing energy consumption. We investigate the effect of nonidealities on the readout operation. We find that when the follower transistor channel-length modulation is taken into consideration, delay is...

The automated circuit breaker diagnostic system described in this paper is an extension of the widely used portable circuit breaker testing device concept. These traditional testing devices can be connected to the circuit breaker’s control circuit to record analog and digital signals. The operator opens and closes the circuit breaker each time the test is performed and makes the recordings. The...

We describe recent progress in the development of a step-based computer-based tutoring system to aid in the teaching of introductory linear circuit analysis courses, and preliminary assessment of its effect on student learning in a controlled trial. The system is based on a software engine that can generate problems with random circuit topologies of specified characteristics as well as full sol...

Matrix Theory has long been applied to many branches of engineering. However, numerical difficulties have limited access to students, especially at the elementary level. This limitation has partially been removed with the development of canned software and modern scientific calculators which operate matrices. However, the approach with matrices ignores this and still follows traditional ways. T...

Failure analysis (FA) plays an important role in the development and manufacturing of integrated circuits. It provides necessary information for technology advancement and for corrective action to improve quality and reliability. In this paper the commonly used techniques in integrated circuits failure analysis are discussed. The paper also describes the basic FA flow consists of fault localiza...

In this paper a new method for increasing the speed of SAGCM-APD is proposed. Utilizing carrier rate equations in different regions of the structure, a circuit model for the structure is obtained. In this research, in addition to frequency response, the effect of added new charge layer on some transient parameters like slew-rate, rising and falling times have been considered. Finally, by tradin...

With recent advances in computational power, scientists can now run thousands of related simulations to explore a single problem. We refer to such a group of related simulations as an ensemble. More generally, an ensemble can be thought of as a set of samples or observations, each consisting of the same set of variables, in a shared high-dimensional space describing a particular problem domain....
