This paper describes recent technology trend of mixed analog digital RF circuits. With the progress of CMOS technology, largescale digital signal process and control function can be integrated in an RF integrated circuit and some analog signal process blocks can be translated to digital signal processing units. At the same time, the design of remaining analog functional blocks becomes very hard...

Introduction: The development of designs for test techniques continue to receive a great deal of consideration [l]. Techniques based on scan is one of the most effective methodologies and has been adopted widely in the area of digital integrated circuit design. When testing systems with scan design, the entire scan registers (SRs) andor combinational modules are always active during the whole s...

Multi-threshold CMOS (MTCMOS) is commonly utilized for suppressing leakage currents in idle integrated circuits. The deactivation/reactivation energy consumption however degrades the effectiveness of the MTCMOS technique for providing significant savings in total energy consumption in CMOS integrated circuits. The sources of mode transition energy consumption in noise-aware MTCMOS circuits are ...

The integrated circuit revolution has impacted virtually all fields of engineering. The main driving force behind this revolution is Complementary Metal-Oxide Semiconductor (CMOS) transistor technology. As CMOS integrated circuit “chips” have come to dominate analog and digital electronics, introductory electronics courses in Electrical and Computer Engineering programs have evolved to place gr...

Integrated Circuit (IC) Technology is growing day by day to enhance the circuit performance and to increase the density for compact systems. Conventional CMOS technology is playing a vital role in digital computation for past four decades. But there are certain challenges in scaling the CMOS devices for the last few years. A novel technology “Quantum dot Cellular Automata (QCA)” has been identi...

Superconductive single-flux-quantum (SFQ) circuit technology attracts attention as a next generation technology of integrated circuits because of its ultra-fast computation speed and low power consumption. In SFQ digital circuits, unlike CMOS digital circuits, a pulse is used as a carrier of information and the representation of the logic values is different from that in CMOS digital circuits. ...

CMOS" refers to both a particular style of digital circuitry design, and the family of processes used to implement that circuitry on integrated circuits (chips). CMOS circuitry in VLSI dissipates less power when static, and is denser than other implementations having the same functionality. As this advantage has grown and become more important, CMOS processes and variants for VLSI have come to ...
