Advances in VLSI fabrication in recent years have greatly increased the levels of integration making possible the implementation of highly complex algorithms such as Viterbi decoders, discrete cosine transforms etc. Smaller integrated circuit device and feature sizes have lead naturally to increased speeds. Expectations and demand have grown for the continuing development of both speed and func...

The short and long term reliability of National Semiconductor’s interface circuits, like any integrated circuit, is very dependent on its environmental condition. Beyond the mechanical/environmental factors, nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every in...

In this paper we have investigated a unified and simultaneous fault detection method for mixed-signal integrated circuits. The method is based on the analysis of the power-supply current through the circuit under test. The analysis has been done paying attention to the dynamic behaviour of the power-supply current, in order to avoid measurement problems related to the large amount of quiescent ...

This paper proposes a field-programmable gate array (FPGA)-based integrated circuit (IC) for computing apparent powers and power factors of power systems. In a nonsinusoidal and unbalanced three-phase power system, the calculation of apparent powers and power factors has many definitions. Load characteristics of harmonic and unbalance can not be expressed in the traditional apparent power and p...

As the technology moves into deep sub-micron region, the power consumption of the integrated circuit will be more. In the current technologies, the leakage power is the major part in the total power consumption. Power gating is a technique which is used to reduce the leakage power by shutting off the idle logic blocks using sleep transistors. Different power gating methods are available now. Th...

A four-device broadband solid-state power amplifier, which is based on radial waveguide power-dividing/combining circuit, has been investigated in this work. The fabricated power amplifier combining four monolithic microwave integrated circuit power amplifiers shows a 12–16.6 dB small-signal gain over a broadband from 6 to 14 GHz. The measured maximum output power at 1 dB compression is 25.6 dB...

Capacitors are important components in many integrated circuits. They serve numerous roles in analog and mixed signal circuits, including switched capacitor filters and sampleand-hold circuits. In addition, capacitors provide a vital role in the decoupling of microprocessors, digital signal processors, and microcontrollers from power supply variations. Traditional integrated circuit capacitors ...

In this paper recent developments of RF front-end system based on the active integrated antenna design concepts are presented. Thanks to the enhancements in the design of special antennas working as radiator as well as providing the other circuit functionalities, the antenna-integrated RF front ends have been capable of improving the circuit-efficiency and compactness. These enhancements are il...
