Experimental Study on Body-Biasing Layout Style
نویسندگان
چکیده
Body-biasing is expected to be a common design technique, then area efficient implementation in layout has been demanded. Bodybiasing outside standard cells is one of possible layouts. However in this case body-bias controllability, especially when forward bias is applied, is a concern. To investigate the controllability, we fabricated a ring oscillator in a 90nm technology, and measured the controllability. Our measurement result and evaluation of area efficiency reveal that body-biased circuits can be implemented with area overhead of less than 1% yet with sufficient speed controllability.

متن کاملExtraction of Nonlinear Thermo-Electroelastic Equations for High Frequency Vibrations of Piezoelectric Resonators with Initial Static Biases
In this paper, the general case of an anisotropic thermo-electro elastic body subjected to static biasing fields is considered. The biasing fields may be introduced by heat flux, body forces, external surface tractions, and electric fields. By introducing proper thermodynamic functions and employing variational principle for a thermo-electro elastic body, the nonlinear constitutive relations an...
متن کاملStyle Versus Substance: Multiple Roles of Language Power in Persuasion
This research explores how message style influences persuasion in conjunction with message substance. Using the elaboration likelihood model, the study operationalizes message style as language power and message substance as argument quality, then considers the multiple roles language power can assume in persuasion. The authors investigate whether language power acts as a (a) central argument, ...
متن کاملThe Effect of DTMOS Transistors on the Performance of a Memristor-based Ternary CAM Cell in Low Power Applications
This paper proposes the use of DTMOS transistors in a memristor-based ternary CAM (MTCAM) instead of MOSFET transistors. It also evaluates the effect of forward body biasing methods in DTMOS transistors on the performance of a MTCAM cell in write mode. These biasing methods are gate-to-body tying (called DT1), drain-to-body tying (called DT2), and gate-to-body tying with a voltage supply of 0.1...
متن کاملGuidelines for Preparing a Paper for the European Conference on Artificial Intelligence
The purpose of this paper is to show a contributor the required style for a paper for AISB 2008. The specifications for layout are described so that non-LTEX users can create their own style sheet to achieve the same layout. The source for the sample file is available for LTEX users. The PostScript and the PDF file is available for all.
