چکیده

&AS TECHNOLOGY SCALES to 22 nm and functional density continues to rise, many factors and parameters have a direct impact on the design and test of chips. Among such challenges, IR-drop and power supply noise (PSN) effects have become more significant in recent years. Design and test engineers need to efficiently handle these effects because they can cause design, test, and reliability issues for the chip. Timing closure and functional verification cannot be considered complete until preand post-layout IRdrop, ground-bounce, and PSN effects have been estimated and the appropriate margins applied. These effects have complex interdependencies, and conventional design tools aren’t capable of considering all of these effects and their interrelationships concurrently. Today’s design and test engineers must deal withmany issues, including the following:

Analysis of IR-Drop Scaling with Implications for Deep Submicron P/G Network Designs

This paper presents a detailed analysis of the power-supply voltage (IR) drop scaling in DSM technologies. For the first time, the effects of temperature, electromigration and interconnect technology scaling (including resistivity increase of Cu interconnects due to electron surface scattering and finite barrier thickness) are taken into consideration during this analysis. It is shown that the ...

Deep-Submicron CMOS Design Methodology for High-Performance Low-Power Analog-to-Digital Converters

In this paper, we present a complete design methodology for high-performance low-power Analog-to-Digital Converters in deep submicron CMOS. This methodology is demonstrated on two ADC architectures, Flash and Folding&Interpolating(F&I). The designs were implemented in 0.18μm CMOS technology, achieving a high conversion rate of 2.6 GSamples/s for the Flash converter, and a 1 GSample/s rate for t...
