The excessive power dissipation is a major obstacle against the further scaling and the enhancement of the integrated circuit technologies. Several new techniques for the design of low power and high performance integrated circuits are proposed in this dissertation. Particular emphasis is placed on suppressing the leakage currents while enhancing the reliability in deeply scaled nanometer CMOS ...

Various low power technologies have been developed and applied to LSIs from the point of device and circuit design. A lot more CPU cores as well as function IPs are integrated on a single chip LSI today. Therefore, not only the device and circuit low power technologies, but software power control technologies are becoming more important to reduce active power of application systems. This paper ...

This paper describes the design and simulation of an innovative monolithic active balun integrated with low noise amplifier. The Single-ended-to-differential signal transformation circuit comprises a differential signal generation circuit, which is able to receive a single-ended signal and generate a pair of signals having a 180o (differential) relationship phase. The fully integrated circuit w...

Powering VLSI die up to 200A in sort test, especially for a structural test system, requires a High Current Device Power Supply (HCDPS) able to provide this amount of current within a very fast response. A new HCDPS structure is implemented to overcome the prober interface constraints and sustain applied voltage during die current transitions with high dI/dt.

Chip Interconnect delay and power is a primary criterion in the design of an Integrated Circuit because of its close connection to the speed of IC. Interconnect Buffers in VLSI circuits is the most widespread procedure used to decrease power and delay but they outcome in high Delay and power dissipation, thereby degrading the performance (i.e.) operating speed of an integrated circuit. Use of b...

in order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. to do this we have investigated optical waveguide both with and without optical pumping. the rate of absorption and emission using an array of algaas/gaas quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. by con...

Quiescent power supply current monitoring (looa) has been shown to be effective for testing CMOS devices. BiCA4OS is emerging as a major technologv for high speed, high performance, digital and mixed signal applications. Stuck-ON faults as well as bridging faults in BiCMOS circuits cause enhanced IDDo. An input pattern classi$ation scheme is presented for detection of stuck-ONhridging faults ca...

Recent advances in Micro-Electro-Mechanical Systems (MEMS) technology, integrated circuits, and wireless communication have allowed the realization of Wireless Body Area Networks (WBANs). WBANs promise unobtrusive ambulatory health monitoring for a long period of time and provide real-time updates of the patient’s status to the physician. They are widely used for ubiquitous healthcare, entertai...

This paper presents an overview of technical challenges in achieving higher integration levels, lower power dissipation, smaller form factor, and lower cost in portable battery-powered RF transceivers for personal communications applications. Specific emphasis is placed on silicon integrated circuits for transceivers in the 800MHz-2.5GHz range of frequencies.
