In this paper we address the growing issue of gate oxide leakage current (Igate) at the circuit level. Specifically, we develop a fast approach to analyze the total leakage power of a large circuit block, considering both Igate and subthreshold leakage (Isub). The interaction between Isub and Igate complicates analysis in arbitrary CMOS topologies and we(More)

In this paper, we analyze the dual-hop amplify-and-forward (AF) and decode-and-forward (DF) relaying systems with multiple interferers over Rayleigh fading channels. We derive closed-form expressions for the outage probability of the dual-hop AF and DF relaying systems with multiple interferers, which have arbitrary transmit power. Numerical results verify(More)
We propose a new method that uses a combined approach of sleep-state assignment and threshold voltage (Vt) assignment in a dual-Vt process. While each of these methods has previously been used individually, their combined effect has not been leveraged to date. By combining Vt and sleep-state assignment, leakage current can be dramatically reduced since the(More)
AS SEMICONDUCTOR DEVICE technology enters the 32-nm era, soft errors are taking center stage in modern SoC and safety-critical embedded-system design. We can overcome failures due to soft errors by various solutions that range from the device level (by designing fault-tolerant circuits) to the architectural level (by adopting various fault-tolerant(More)
There are growing needs for the 3D environment. The 3D devices, such like 3D television, have already started to be sold in markets to the general public. In other words, it means that 3D environment is becoming accustomed to everything. In the same manner, the ways for the 3D manipulation are also getting more important, and there are lots of ways for the(More)
In this paper, we address the problem of signal pruning in static timing analysis (STA). Traditionally, signals are propagated through the circuit and are pruned, such that only the signal with the latest arrival time at each node is propagated forward. This sig-nal pruning is a key to the linear run time of STA. However, it was previously observed that a(More)
In this paper we develop a fast approach to analyze the total leakage power of a large circuit block, considering both gate leakage, Igate, and subthreshold leakage, Isub. The interaction between Isub and Igate complicates analysis in arbitrary CMOS topologies. We propose simple and accurate heuristics to quickly estimate the statedependent total leakage(More)
In this paper, a decode-and-forward (DF) opportunistic relaying is investigated in a multicell environment with intercell interference. The outage-optimal relay selection is investigated, and the closed-form expressions of the exact and the approximate outage probabilities are derived for the DF opportunistic relaying in a multicell environment over(More)
Cooperative transmission obtains the spatial diversity gains created by sharing antennas of terminals in wireless networks. Although the amplify-and-forward (AF) cooperative transmission has the advantages of low implementation complexity and simplicity compared to the decode-andforward (DF) cooperative transmission, studies on the AF cooperative(More)
