In this paper we discuss the application of domain decomposition methods to circuit simulation. This coarse grain pamldelization guarantees low communication and thus achieves good speedup results on a workstation cluster. Especially with multi level Newton methods and iteration latency techniques, the communicatiolz can be reduced to a minimum. The application of these techniques make our para...

ABSTRACT The paper provides a complete analysis of the APS pixel and column circuit delay. Contrary to common belief, we show that shorter settling times can be achieved by reducing the bias current and hence reducing energy consumption. We then investigate the effect of non-idealities on the readout operation. We find that when the follower transistor channel length modulation is taken into co...

In this paper an analysis on the oversampling data recovery circuit is presented. The input waveform is assumed to be non-return-zero (NRZ) binary signals. A finite Markov chain model is used to evaluate the steady-state phase jitter performance. Theoretical analysis enables us to predict the input signal-to-noise ratio (SNR) versus bit error rate (BER) of the oversampling data recovery circuit...

A simple, general, yet realistic MOSFET model, namely the nth power law MOSFET model, is introduced. The model can express I -V characteristics of short-channel MOSFET's at least down to 0.25-pm channel length and resistance inserted MOSFET's. The model evaluation time is about 1 / 3 of the evaluation time of the SPICE3 MOS LEVEL3 model. The model parameter extraction is done by solving single ...

This dissertation presents a novel verification technique for analog and mixed signal circuits. Analog circuits are widely used in many applications such as consumer electronics, telecommunications, medical electronics, and so on. Furthermore, in deep sub-micron design, physical effects might undermine common digital abstractions of circuit behavior. Therefore, it is necessary to develop system...

In the past two decades, modal analysis has become a major tool in the quest for determining, improving and optimizing dynamic characteristics of engineering structures. Not only has it been recognized in mechanical and aeronautical engineering, but also modal analysis has discovered profound applications for civil and building structures, biomechanical problems, space structures, acoustical in...

This paper presents a theory of corn monsense understanding of the behavior of electronic circuits. It is based on the intuitive qualitative reasoning electrical engineers use when they analyze circuits. This intuitive reasoning provides a great deal of important information about the operation of the circuit, which although qualitative in nature, describes important quantitative aspects of cir...

We present an analysis of the bass drum circuit from the classic Roland TR-808 Rhythm Composer, based on physical models of the device’s many sub-circuits. A digital model based on this analysis (implemented in Cycling 74’s Gen ̃) retains the salient features of the original and allows accurate emulation of circuit-bent modifications—complicated behavior that is impossible to capture through bla...
