Abstract:

The use of dual-gate field-effect transistors located on the base matrix crystal MH2XA031, controlled by a p–n junction needed to reduce the input current of operational amplifiers is studied. Typical circuits of operational amplifiers, containing: source repeaters connected to the inputs of the operational amplifier on complementary bipolar transistors; input differential stage on p-JFET with a “current mirror” load on n–p–n-transistors; input differential in the form of a “folded cascode” on a p-JFET are analyzed. To minimize the input current, it is re commended to use bootstrapped feedback

Quantum-dot Cellular Automata (QCA) as a nanoscale transistor-less device technology offers distinguishing advantages over the limitations of CMOS circuits. This nanoelectronic is based on the mapping of binary logic in the two excess electrons configuration within a four-dot cell. In this paper, we propose a new ultra-low energy and low-complexity two-input XOR gate which can be employed as a basic component in designing a wide range of QCA logical circuits.

An optical isolator circuit is developed to detect and dynamically relocate the photovoltaic (PV) module under partial shading. The suggested system control structure operates in two modes.

Mode 2 detects and separates all the bypassed modules from a PV string/array by means of a decentralized control and stores its power in the battery.

Abstract:

The degradation effect of a field-programmable gate array becomes a significant issue due to the high density of logic circuits inside the field-programmable gate array. The degradation effect occurs because of the rapid technology scaling process of the field-programmable gate array while sustaining its performance. One parameter that causes the degradation effect is the delay occurrence caused by the hot carrier injection and negative bias temperature instability. As such, this research proposed a multipoint detection technique that detects the delay occurrence caused by the hot carrier inje

Abstract:

Recently, the threat of hardware Trojans has garnered attention. Hardware Trojans are malicious circuits that are incorporated into large-scale integrations (LSIs) during the manufacturing process. When predetermined conditions specified by an attacker are satisfied, the hardware Trojan is triggered and performs subversive activities without the LSI users even being aware of these activities. In previous studies, a hardware Trojan was incorporated into a cryptographic circuit to estimate confidential information. However, Trojan triggers have seldom been studied. The present study develops sev

Abstract:

Probabilistic computing is an emerging computational paradigm that uses probabilistic circuits to efficiently solve optimization problems such as invertible logic, where traditional digital computations are difficult to solve. This paper proposes a true random number generator (TRNG) based on resistive random-access memory (RRAM), which is combined with an activation function implemented by a piecewise linear function to form a standard p-bit cell, one of the most important parts of a p-circuit. A p-bit multiplexing strategy is also applied to reduce the number of p-bits and improve resource u

Abstract:

The logic blocks of Field Programmable Gate Array (FPGA) basic unit are mainly composed of Look-Up-Tables (LUTs). The traditional LUTs use the static random access memory (SRAM), which causes FPGA reach the limitation in term of the density, speed, and configuration overhead. In this paper, a novel nanometer memristor-based LUT (NMLUT) is composed of memristors, MOS field effect transistors, decoders, resistors. A three-input NMLUT and a four-input NMLUT circuits are investigated. Moreover, an adder is used to verify the practicality of NMLUT circuit. The proposed NMLUT circuit can implement s

Abstract:

Breathing is an important physiological process in the human body. The wavelet transform method can extract respiratory information from electrocardiogram (ECG) data; thus, the authors designed an integrated circuit of ECG-derived respiration (EDR). They propose a discrete wavelet transform (DWT) EDR algorithm based on an analysis of the heartbeat frequency and respiration. They verified the algorithm in both the time domain and the frequency domain using Matlab. Next, the DWT EDR digital circuit was designed using the QUARTUS program. Finally, they used a field programmable gate array (FPGA)

The on-chip integration of multiple biochemical sensors based on field-effect electrolyte-insulator-semiconductor capacitors (EISCAP) is challenging due to technological difficulties in realization of electrically isolated EISCAPs on the same Si chip. In this work, we present a new simple design for an array of on-chip integrated, individually electrically addressable EISCAPs with an additional control gate (CG-EISCAP). The existence of the CG enables an addressable activation or deactivation of on-chip integrated individual CG-EISCAPs by simple electrical switching the CG of each sensor in va

A Finite-State Machine (FSM) model is frequently employed to represent the behavior of sequential circuits. In the optimal design of these circuits, it is crucial to enhance FSM characteristics such as area (implementation cost), performance (operating frequency), and power consumption. This paper proposes sequential state encoding methods that aim to reduce the area and enhance the performance of FSMs. The methods involve sequentially selecting FSM states for encoding and determining the most appropriate code for each selected state.

Abstract:

The memristor is the fourth fundamental element in the electronic circuit field, whose memory and resistance properties make it unique. Although there are no electronic solutions based on the memristor, interest in application development has increased significantly. Nevertheless, there are only numerical Matlab or Spice models that can be used for simulating memristor systems, and designing is limited to using memristor emulators only. A memristor emulator is an electronic circuit that mimics a memristor. In this way, a research approach is to build discrete-component emulators of memristors

Although memristor process technology is the best alternative to synapses, it is still undergoing refinement.

Abstract:

Most modern pulsed laser systems require versatile laser diode drivers. A state-of-the-art pulsed laser driver should provide precise peak power regulation, high repetition rate, and pulse duration control. A new, charge line dual-FET transistor circuit structure was developed to provide all these features. The pulsed modulation current is adjustable up to Imax = 1.2 A, with the laser diode forward voltage acceptable up to UF max = 20 V. The maximum repetition rate is limited by a charge line circuit to frep max = 20 MHz. Compared to the conventional single transistor drivers, the solution pro
