Analog design requires simulation comprehending detailed and accurate semiconductor process knowledge in order to produce designs which will (one hopes) meet narrowly defined specifications. QED The fault simulation is already done! ((Quod erat demonstrandum = which was to be demonstrated.) for those, like me, wondering what the latin acronym means...) Model-to-hardware correlation is a require...

conclusions prophylactic gabapentin administration could be considered as an effective and safe intervention to reduce occurrence and severity of plsp after gynecologic laparoscopic cystectomy. results comparing the gabapentin (n = 20) and placebo (n = 20) groups, basic characteristics including age (p = 0.446), body mass index (bmi) (p = 0.876), pregnancy history (p = 0.660), and surgery time ...

fibrates, as hypolipidemic drugs known as agonists of peroxisome proliferator-activated receptors, diminish inflammatory responses. studies have shown that incorporation of a silicon atom into a drug structure improves its pharmacological potency, modifies its selectivity toward a given target, or changes its metabolic rate, in addition to increasing the lipophilicity of the compounds. a silico...

Analog and mixed signal design has always been very interesting and when it comes to the design of high-speed CMOS and SiGe BiCMOS optical transceivers it becomes even more challenging. Special care has to be taken while doing the layout of such a circuit that operates at a frequency of 1 Gbps or higher. The focus of our first work was to layout an optical driver and receiver stage capable of h...

The automated circuit breaker diagnostic system described in this paper is an extension of the widely used portable circuit breaker testing device concept. The testing devices can be connected to the circuit breaker’s control circuit to record analog and digital signals. The automated system consists of a signal processing module and an expert system module. The two modules process the voltage ...

− This paper presents the new self-testing method for diagnosis of analog parts in mixed-signal embedded systems controlled by microcontrollers. The tested analog part is stimulated by a sinus-wave supplied by the onboard generator and its responses are sampled in selected nodes by microcontrollers ADC. The measurement space is represented by differences between values of selected node voltages...

In this letter a histogram-based BIST (Built-In Self-Test) approach for deriving the main characteristic parameters of an ADC (Analog to Digital Converter) such as offset, gain and non-linearities is proposed. The BIST uses a ramp signal as an input signal and two counters as a response analyzer to calculate the derived static parameters. Experimental results show that the proposed method reduc...

The article describes a new method of Analog-toDigital Converters testing that is suitable for testing of highresolution AD converters (e.g. Σ-∆ or dither-based) or on the contrary ultra high-speed AD converters. The method is based on the histogram test driven by stochastic signal with defined probability density function. By repeating of the test for different settings of band-pass filter tha...

The paper deals with the problems of modeling and testing of pipeline ADCs. In particular, such problems are faced through the realization of a modular Virtual Instrument. It has been developed in Java language in order to be remotely manageable through a common Internet browser. The instrument features includes (i) a module able in modeling an ADC through the specialization of a simplified beh...
