Worst-case design uses extreme process corner conditions which rarely occur. This limits maximum speed specifications and costs additional power due to area over-dimensioning during synthesis. We present a new design synthesis strategy for digital CMOS circuits that makes use of forward body biasing. Our approach renders consistently a better performance-per-area ratio by constraining circuit over-dimensioning...
This paper presents a new dynamic circuit design style based on the differential cascade voltage swing logic. The design style is proposed as a data driven dynamic differential logic design style. The proposed design style offers significant performance advantages over conventional DCVSL and Differential Domino with reduced power consumption. The pre-charge and evaluation phases are controlled by...
Subthreshold region of operation has gained wide research interest for applications requiring Ultra low power consumption and medium frequency of operation. Double gate MOSFETs are proved to be better candidates for subthreshold operation due to their near ideal subthreshold slope and negligible gate capacitance. However it is not yet clear whether symmetric (SDG) or Asymmetric (ADG) DG with options...
The performance of arithmetic adders varies widely in their power consumption, delay, and area requirements. To acquire more fine-grained tradeoffs in the power-delay tradeoff curve of a binary adder, the heterogeneous adder architecture is adopted. In heterogeneous adder architecture, a binary adder is decomposed into sub-adder blocks with different carry propagation schemes and precisions. Thus...
This paper analyzes the performance of a quaternary logic circuit and its components. The multi-valued logic design consisting of two drivers and a transistor matrix is simulated using Mentor Graphic software. Functional operation of the circuit is shown and propagation delay and power consumption are determined. The design is dependent on the voltage values for the multi-valued logic. Three logic...
