The noninvasive efficient diagnosis of heart is possible through the study of electrocardiogram (ECG) of the patient under observation. A single system is necessary to know about few diseases based upon ECG data of the person and other parameters. Here, a new technique has been proposed which will measure kidney and heart disease depending on creatinine and urea nitrogen levels. This technique will detect the diseases in prior to reach the severe condition of their health. The MIT-BIH database has been considered as a reference for ECG signals and MATLAB version 8.2 was used to display the results.

It has all the information related to the electrical activities of heart. This also has the information of normal and abnormal activities for the detection of the diseases. So it is essential and important to detect the accurate R-peaks in QRS complex, especially when the results are to be used for clinical applications. Hence in a long-term ECG signal, automatic R-peaks detection is very essential to diagnose cardiac disorders. In this paper we proposed a robust technique to detect R-peak which uses Wavelet Transform. The proposed R Peak detector is consists of a wavelet filter banks, a noise detector with zero-crossing points, multi-scaled product algorithm and soft-threshold algorithm.

Numerous methods have been developed with still-ongoing modifications and ideas to observe and evaluate ECG signals based on each heart beat. The majority of research revolves around arrhythmia classification, heart rate monitoring and blood pressure measurements that require highly accurate assessments of rhythm disorders which can be possible by measuring QRS complex of ECG signals, so accurate QRS detection methods are very important to be utilized. There have been proposed many approaches to find out the R peak detection to analyze the ECG signals in the past few years. Most recent and efficient techniques of R peak detection have been reviewed in this paper. Techniques which have been reviewed in this paper are Pan and

The OPAMP which has been designed is two stage CMOS OPAMP followed by an output buffer. The op-amp which has been designed, exhibits a unity gain frequency of 14MHz and a gain of 77.25dB with 85.85 phase margin. A new technique which takes into account the effect of transfer function zeros, which are traditionally neglected, has been proposed. The simplest frequency compensation technique employs the Miller effect by connecting a compensation capacitor across the high-gain stage. The compensation method results in higher unity gain bandwidth under the same load condition. Both the theoretical calculations and computer aided simulation analysis have been given in detail. Design has been carried out in Mentor graphics tool. Simulation results have been verified using Model Sim Eldo and Design Architect IC.

This paper describes the comparator circuits used in most of the analog circuits now-adays. Comparators play a vital role in most of the analog circuits like Flash ADC’s and the performance of these circuits is greatly influenced by the choice of comparators. In this paper, first a “ Open loop comparator” is designed and its analysis is done followed by a “TIQ comparator”, “Quantized Differential Comparator”, “Two stage CMOS amplifier with an output inverter” and “CMOS-LTE Comparator” and all of these circuits are used for implementing a lot low power analog circuits. After implementing all the comparator circuits, power and delay analysis has been done on the basis of which Power-Delay-Product (PDP) has been calculated. All the above circuits are implemented using 180nm CMOS technology using a supply voltage of 1.8v. T...
