Monolithic 3D integrated circuits using transition metal dichalcogenide materials and low-temperature processing are reported. A variety of digital and analog circuits are implemented on two sequentially integrated layers of devices. Inverter circuit operation at an ultralow supply voltage of 150 mV is achieved, paving the way to high-density, ultralow-voltage, and ultralow-power applications.
In this paper, a quadrature phase shifter is presented. Due to operation in current-mode, the proposed circuit provides a wide frequency response, a low supply voltage, low power consumption and electronic controllability. Thus, it is very suitable for use in portable and battery-powered equipment such as hearing aid instrument and wireless radio device. The proposed quadrature phase shifter co...
Accelerometers have a wide range application in many fields, such as airbag deployment system and electronic stability control system in vehicles, and inertial navigation system in aircrafts and rockets. As MicroElectro-Mechanical System (MEMS) technology advances, accelerometers are made smaller and smaller, often integrated in a single chip, with lower implementation costs and power consumpti...
Gallium–nitride power transistor (GaN HEMT) and integrated circuit technologies have matured dramatically over the last few years, and many hundreds of thousands of devices have been manufactured and elded in applications ranging from pulsed radars and counter-IED jammers to CATV modules and fourth-generation infrastructure base-stations. GaN HEMT devices, exhibiting high power densities coupl...
Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...
State-of-the-art microprocessors as well as Digital-Signal Processing (DSP) circuits demand power supplies to be quick, accurate, and capable of delivering high currents. Additionally, portable battery-powered applications, like laptop computers, require these Integrated Circuits (IC's) to be power efficient to extend battery life. In terms of speed, which also translates to accuracy, of course...
this paper presents a new arc starter circuit that is usable in manual metal arc welding (mma) power supplies. the proposed circuit uses an auxiliary circuit and a series coupling transformer for adding high frequency spikes to output dc voltage during arc striking. the proposed circuit is usable in inverter based arc welding supplies and it could result in a decrease of weigh, volume and expen...
In any integrated circuit power consumption plays a paramount role and is considered as one of the top challenges in International technology roadmap for semiconductors. In this paper, a low power circuit designed to operate in subthreshold region is proposed. Voltage scaling technique is incorporated to reduce dynamic power consumption while static or leakage power is greatly reduced with forc...
