Background Anemia is a significant global health concern, often stemming from iron deficiency or deficiencies in folate, vitamins B12, and A. Anemia disproportionately impacts vulnerable populations like children, adolescent girls, and pregnant or postpartum women. Purpose Anemia is a serious public health issue, impairing productivity, cognitive...

It gives an innovative strategy for detecting and preventing fraud in banking applications, with a specific focus on incorporating face recognition technology. In this proposed methodology, a Seagull-based convolutional neural network (SbCNN) is utilized to tackle crucial challenges related to facial recognition, especially in scenarios where indiv...

The characteristic features of brain magnetic resonance image (MRI) scans of Alzheimer’s disease (AD) patients and normal controls (NC) are difficult to differentiate because of very similar brain patterns and image intensities at the initial stages. Thus, it is difficult to detect AD at earlier stages. The earlier detection can lead to earlier med...

The most modern internet innovation, known as the "Internet of Things" (IoT), continuously broadcasts real-time data on the state of the entire planet, including details on humidity, temperature, thunderstorms, earthquakes, floods, and other conditions that potentially jeopardise human life. Our study suggests a low cost weather informative and mon...

The operational amplifier (op amp) design in very deep submicron technology endure the barriers like exponential increase in leakage current, process variations, quantum–mechanical tunnelling, and lithographic limitations. This results in low gain stages and decreased impedance thereby degrading the performance of op amp. In order to provide improv...

Abnormal movement and unconsciousness are responsible for the generation of seizures which in turns causes temporary loss of control. Seizures observed due to sudden abnormal electrical discharges in the brain are epileptic seizures. The stress-related seizures are referred to as psychogenic non-epileptic seizures (PNES) and other non-epileptic sei...

The folded cascode operational amplifier (FCOA) designed in this paper is the single-pole operational amplifier (op amp). In this design, the conventional current mirror is replaced with wide swing current mirror to overcome the essential drawback of cascode configuration. In this paper, negative feedback is used to improve the small-signal gain an...

Single-pole operational amplifiers are majorly characterized as constant gain and stable operational amplifiers. Folded cascode amplifier falls in such category of single-pole operational amplifier with high gain and improved output swing, maintaining constant phase margin for stable operation. Stability is even better in this case, compared to mul...

Carbon nanotube (CNT) is one of the embryonic technologies within recent inventions towards miniaturization of semiconductor devices and is gaining much attention due to very high throughput and very extensive series of applications in various analog/mixed signal applications of today’s high-speed era. The carbon nanotube field effect transistors (...

This paper presents the design and verification of folded cascode operational amplifier using conventional CMOS technology. The design specification has been decided and accordingly the aspect ratios are designed with the help of design equations. Design have been carried out on Mentor Graphics EDA tool using TSMC 180nm and 130nm, 32nm on HSPICE ED...

Fingerprint authentication is one of the most reliable and widely used personal identification method. However, manual fingerprint authentication is tedious, inaccurate, time-consuming and costly that it is not capable of meeting today's increasing performance necessities. An automatic fingerprint authentication system (AFAS) is widely needed. It p...

The market demand and efficient portable electronic equipment have pushed the industry to produce circuit designs operating at low voltage (LV) for low power (LP) consumption. Reducing the supply voltage reduces the dynamic power quadratic ally and leakage power linearly to the first order. Hence, supply voltage scaling has remained the major focus...
