ECG or Electrocardiograph is a tool to find out the electrical activity of heart in patients. Electrocardiogram (ECG) graphic result records potential resulting from by heartbeat, (Mervin J. Goldman, 1990). recording very useful know present certain hypertrophy, arrhythmia, pericarditis, for example potassium electrolyte disturbances. Tool this be named generator signal ECG. functioning produce...

Abstrac tContinuous-Time delta sigma modulators (CT ∆ΣM), by their nature, are mixed-signal systems. That fact creates a discontinuity in the traditional IC design flow which assumes that “discrete” and “continuous” time domain designs require separate design tools. In this work, we present a top level behavioral approach of modeling CT complex Bandpass (CBP) ∆ΣM using VHDL-AMS language. The CT...

Boris Murmann Stanford University In the past, CMOS feature size scaling has played a big role in overcoming the perceived barriers, routinely enabling cheaper, faster and lower power devices with every new technology node, However, as the benefits of conventional feature size scaling are diminishing, what can we do to meet the needs of next-generation systems? The precise answer to this questi...

An effective novel approach for built in self test is proposed in this paper, which is useful in Mixed signal IC testing (here CPPLL). The approach is useful in digital testing applications which can detect the fault in any of the block that is phase frequency detector, VCO, loop filter, or charge pump. The key advantage of this approach is that it uses all the existing elements for measuring a...

The integrated circuit revolution has impacted virtually all fields of engineering. The main driving force behind this revolution is Complementary Metal-Oxide Semiconductor (CMOS) transistor technology. As CMOS integrated circuit “chips” have come to dominate analog and digital electronics, introductory electronics courses in Electrical and Computer Engineering programs have evolved to place gr...

A novel approach to the dynamic supply current sensing based on the measurement of voltage drop across a parasitic resistance of the supply voltage metal line is presented. Then, auto-zero technique for voltage comparator offset cancellation, which provides very accurate and sensitive low voltage measurement is proposed. Therefore, we may use this as a current monitor for dynamic current testin...

The major goal of our work was to develop an efficient defect-oriented parametric test method for analog & mixed-signal integrated circuits based on Artificial Neural Network (ANN) classification of a selected circuit’s parameter using different methods of signal preprocessing. Thus, ANN has been used for detecting catastrophic defects in an experimental mixedsignal CMOS circuits by sensing the...

In a response to today’s trend in technology, the theoretical focus of most digital and analog based circuit courses is shifting towards CMOS technology. Due to the lack of proper laboratory testing circuits and environments for CMOS technology; older, obsolete circuits are used in many laboratory classes. While these labs afford students the chance to compare classroom analysis to real laborat...

Abstract In this paper, the methodological aspects for the design of mixed-signal map-configurable chaos generators are presented. Such techniques have been applied in the integration, embedded in a complete FM-DCSK modem, of a chaos ge...

Area and Power consumption are important design metrics in integrated circuit (IC), in particular in those targeted for wearable devices. Σ-∆ Analog to Digital Converter (ADC) are increasing in popularity in those devices thanks to the low bandwidth of a great number of sensors that permits to increase converter performances by the oversampling and noise shaping techniques. One of the most impo...
