Contemporary society electronic technology has evolved into a pivotal component across various facets of our lives. Its indispensability is particularly evident in the advancement of medical, agricultural, industrial, and other sectors. As this technology continues to play a crucial role, optimizing its performance in terms of speed, accuracy, and...

Decimal arithmetic is gaining more attention by researchers due to their importance in many human-centric applications. Hardware implementations of decimal arithmetic are preferable over their software counterparts as the former leads in performance especially when it comes to real-time applications. Decimal addition is a main decimal operation as...

Data converters are necessary for the conversion process of analog and digital signals. Successive approximation register (SAR) analog-to-digital converters (ADC) can achieve high levels of accuracy while consuming relatively low amounts of power and operating at relatively high speeds. This paper describes a design of 8-bit 125 kS/s SAR ADC with a...

This paper presents a novel approach to designing a CMOS inverter using the Mayfly Optimization Algorithm (MA). The MA is utilized in this paper to obtain symmetrical switching of the inverter, which is crucial in many digital electronic circuits. The MA method is found to have a fast convergence rate compared to other optimization methods, such as...

Decimal arithmetic gains its importance in different applications in the fields of finance and scientific applications. The approach of running decimal arithmetic over binary hardware requires conversions from decimal to binary and from binary to decimal. These conversions produce inexact results that impose financial losses for companies. Therefor...

The surrounding world is composed of continuous time and amplitude analog signals, such as the sound signal picked by a microphone, the light entering a camera, the temperature measured by a thermocouple. In order to process these real world signals by computers, they have to be converted to digital signals. Rapid advances in media technology requi...

Increased demand for intelligence in high performance applications such as home appliance, transportation, renewable energy systems, medical equipment and utilities interfaces, while managing cost, efficiency and volume is a challenge for inverter topologies. In addition, increased efficiency and optimal operation require complex control schemes, w...

In distributed sensor networks (DSNs), localization errors are highly dependent on the relative location of sensors with respect to the target of interest. In this paper, we study the problem of relocating sensors from their initial deployment positions to new positions that would result in meeting estimation requirements at multiple points in a re...

In RSSI-based target localization, estimation error depends on several factors (e.g., location of sensors, target energy). Furthermore, when quantization is involved, localization accuracy largely depends on the number of allocated bits and quantization thresholds used by each sensor. In this paper, we consider the problem of meeting estimation err...

Gain and offset represent two important measures to determine the accuracy of a comparator. Thus, analysis on these parameters is very important as they offer designers better under- standing of the circuit and allow exploring trade-offs during design. In this paper, two methods were presented to derive a set of design equations that describe the g...

This paper presents a new digitally-assisted analog foreground comparator offset calibration technique that is fast, compact, low-power, precise, and linear. Non-linear input referred DC offset voltage of a comparator used in an analog-to-digital converter (ADC) is considered as the most important factor that degrades performance, especially for AD...

A two-step offset correction technique for high precision comparator design is proposed. The two step coarse-fine calibration (CFC) technique provides precise offset correction much faster than a single step calibration and the circuit implementation is less complicated. The proposed two step calibration technique was employed on a two-stage dynami...

In recent years, the necessity for fast, accurate and less memory-intensive techniques to analyze nonlinear circuits has grown as technology has advanced. The harmonic balance (HB) method is a powerful tool and it has been used for some time in nonlinear circuit analysis. In order to keep up with the vast requirements of circuit design, the harmoni...
