Estimating and minimizing the maximum power dissipation during testing is an important task in VLSI circuit realization since the power value affects the reliability of the circuits. Therefore during testing a methodology should be adopted to minimize power consumption. Test patterns generated with –D 1 option of ATALANTA contains don’t care bits (x bits). By suitable filling of don’t cares can...

GaN integrated circuit technologies have dramatically progressed over the recent years. The prominent feature of high-electron mobility transistors (HEMTs), unparalleled output power densities, has created a paradigm shift in established and emerging high-power applications. In this article, we present review on developments prospects amplifiers (PAs). progress including improvements their impo...

Computer-aided design (CAD) tools are frequently employed to verify the design objectives before the fabrication of an integrated circuit. An important circuit parameter that requires accurate characterization is the power consumption due to the strict constraints on the acceptable power envelope of integrated systems. Circuit simulators typically provide built-in functions to measure the power...

Many people are trying to be smarter every day. How's about you? There are many ways to evoke this case you can find knowledge and lesson everywhere you want. However, it will involve you to get what call as the preferred thing. When you need this kind of sources, the following book can be a great choice. sub threshold design for ultra low power systems integrated circuits and systems is the PD...

This paper deals with the electromagnetic emissions of integrated circuits. In particular, four measurement techniques to evaluate integrated circuit conducted emissions are described in detail and they are employed for the measurement of the power supply conducted emission delivered by a simple integrated circuit composed of six synchronous switching drivers. Experimental results obtained by e...

This paper provides a comparative study of the proposed global clock distribution methods for high-speed digital integrated circuits. Both non-networked and distributed schemes such as travelling and standing wave clock distributions have been reviewed. Performance metrics are described and qualitatively discussed and non-networked approaches were simulated in a low-power 65nm CMOS process.

This paper presents an optimized knowledge-based design approach for design of analog integrated circuits. The proposed design approach uses gm/ID technology characteristic in order to find the transistor dimensions (W, L) and drain currents. This method employs the gm/ID characteristic curve versus normalized drain current In=ID/(W/L) to calculate the design variables such as width (W) and len...

We propose a CMOS circuit that can be used as an equivalent to resistors. This circuit uses a simple differential pair with diodeconnected MOSFETs and operates as a high-resistance resistor when driven in the subthreshold region of MOSFETs. Its resistance can be controlled in a range of 1–1000 MΩ by adjusting a tail current for the differential pair. The results of device fabrication with a 0.3...

A high-linearity and high-efficiency MMIC power amplifier is demonstrated adopting a new on-chip adaptive bias circuit, which improves efficiency at the low output power level and linearity at the high output power level automatically. The intelligent two-stage W-CDMA power amplifier using the newly proposed adaptive bias circuit extends the maximum linear output power of 0.6dB and exhibits an ...
