چکیده

Static power consumption is nowadays a crucial design parameter in digital circuits due to emergent mobile products. Leakage currents, the main responsible for static power dissipation during idle mode, are increasing dramatically in sub-100nm processes. Subthershold leakage rises due to threshold voltage scaling while gate leakage current increases due to scaling of oxide thickness. It means the static power dissipation should be considered as soon as possible in the design flow. Leakage mechanisms and reduction techniques will be reviewed, providing a minimum background about this issue.

Suppression of Gate Induced Drain Leakage Current (gidl) by Gate Workfunction Engineering: Analysis and Model

Leakage current reduction is of primary importance as the technology scaling trends continue towards deep sub-micrometer regime. One of the leakage mechanisms which contribute significantly to power dissipation is the Gate Induced Drain Leakage (GIDL). GIDL sets an upper limit on the VLSI MOSFET scaling and may even lead to device breakdown. Thus, in order to improve performance, static power c...

A New Circuit Scheme for Wide Dynamic Circuits

In this paper, a new circuit scheme is proposed to reduce the power consumption of dynamic circuits. In the proposed circuit, an NMOS keeper transistor is used to maintain the voltage level in the output node against charge sharing, leakage current and noise sources. Using the proposed keeper scheme, the voltage swing on the dynamic node is lowered to reduce the power consumption of wide fan-in...

A Novel Circuit Design Technique to Minimize Sleep Mode Power Consumption due to Leakage Power in the Sub-100nm Wide Gates in CMOS Technology

With the rapid scaling down of CMOS manufacturing technology, the reduction in leakage power has become an important concern in low voltage, low power and high performance applications. In this paper a novel circuit design technique is presented which minimizes sub-threshold leakage current by zeroing drain-source voltage. This results in a reduction of leakage power consumption in sleep mode e...

Pattern Generation for Composite Leakage Current Maximization

There are three major sources of leakage current today, namely the sub-threshold leakage, gate leakage and the reverse biased junction band-to-band-tunneling leakage. These currents depend on the logic state of a CMOS circuit as determined by input pattern. Consequently, there exists a pattern that will produce the highest leakage current. Previously, researchers have investigated the problem o...
