In this paper we present a novel reversible implementation of a square-root circuit with an array structure. In scientific computations such as numerical analysis, computer graphics, complex number computations, square root is an important operation. In classical irreversible arena we find different realizations of square root circuit. Since reversible circuit is emerging as an alternative to classical...
A low cost Ultra Low Voltage design implemented using standard CAD tools with adapted margins is presented. Critical path replica rings have been measured to ensure models validity at ultra-low voltages, on the 0°C to 50°C temperature range. The observed behavior and mismatch compared to CAD simulations enabled us to define the margins to be used for the standard circuit implementation flow. We then...
This paper presents a switched-capacitor simulator, optimized for fast computations. Two CAD tools are implemented in order to perform Monte-Carlo simulations, to identify sensitive parasitic coupling prior to layout and to rapidly verify parasitic coupling from an existing layout. Simulation results and measurements on a ΣΔ ADC are compared to validate the tools1.
In this paper we show that the test data compression achieved by a dictionary based method can be improved significantly by suitably reusing parts of the dictionary entries. To this end two new algorithms are proposed, suitable for partial and complete dictionary coding respectively. The efficiency of the proposed techniques is supported with extensive simulation results.
