    The work described in this thesis is aimed at the exploration of new methods\ud for the integration of design and test development procedures for mixedsignal\ud integrated circuits (IC's). Mixed-signal IC's are currently found in\ud many electronic systems, including telecommunications, audio and video\ud instruments, automotive parts, etc. The testing of these IC's presents\ud problems due to the complex nature of analog functionality and the nonautomated\ud analog design process. Automatic generation of test programs\ud for analog parts is a problem which is not yet fully solved. Once a test is\ud generated, formal methods to ensure the quality of developed tests do not\ud exist or have a large overhead. Systematic links between design and test\ud development processes of analog and mixed-signal circuits are required to\ud improve these points and to ensure high quality and low time-to-market\ud (TTM) for mixed-signal IC's

    Quantum arithmetic operations based on quantum Fourier transform on signed integers

    The quantum Fourier transform (QFT) brings efficiency in many respects, especially usage of resource, for most operations on quantum computers. In this study, the existing QFT-based and non-QFT-based quantum arithmetic operations are examined. The capabilities of QFT-based addition and multiplication are improved with some modifications. The proposed operations are compared with the nearest quantum arithmetic operations. Furthermore, novel QFT-based subtraction, division and exponentiation operations are presented. The proposed arithmetic operations can perform nonmodular operations on all signed numbers without any limitation by using less resources. In addition, novel quantum circuits of two's complement, absolute value and comparison operations are also presented by using the proposed QFT-based addition and subtraction operations.Comment: 23 pages, 38 figures, Accepted by International Journal of Quantum Information on Sep 3, 2020, Online Ready on Oct 8, 202

    Input-output connections between sectors and optimal monetary policy

    This paper considers the monetary policy implications of a model that features input-output connections between stages of production, so that a distinction between CPI inflation and PPI inflation arises. More specifically, this paper addresses the policy conclusion by K. Huang and Z. Liu [2005, "Inflation targeting: What inflation rate to target", Journal of Monetary Economics 52], which states that central banks should use an optimal inflation index that gives substantial weight to stabilising both CPI and PPI. This paper argues that these authors' findings rely on the assumption that producer prices are as sticky as consumer prices and it also shows that, once empirically relevant frequencies of price adjustment are used to calibrate the model, CPI inflation receives substantial weight in the optimal inflation index. Moreover, this rule is remarkably robust to uncertainty regarding the model parameters, whereas the policy rule proposed by Huang and Liu can result in heavy welfare lossesInflation targeting, Optimal Monetary Policy

    An integrated model for cash transfer system design problem

    Get PDF
    This paper presents an integrated model that incorporates strategic, tactical, and operational decisions for a cash transfer management system of a bank. The aim of the model is to decide on the location of cash management centers, number and routes of vehicles, and the cash inventory management policies to minimize the cost of owning and operating a cash transfer system while maintaining a pre-defined service level. Owing to the difficulty of finding optimal decisions in such integrated models, an iterative solution approach is proposed in which strategic, tactical, and operational problems are solved separately via a feedback mechanism. Numerical results show that such an approach is quite effective in reaching greatly improved solutions with just a few iterations, making it a promising approach for similar integrated models

    Optimal monetary policy in the generalized Taylor economy

    In this paper we use the Generalized Taylor Economy (GTE) framework in which there are many sectors with overlapping contracts of different lengths to analyze the design of monetary policy. We derive a utility based objective function of a central bank for this economy and use it to evaluate the performance of alternative simple rules. We find that a simple rule that targets an index that gives more weight to the sectors which have longer contracts and are more important in the aggregate index yields a welfare outcome nearly identical to the optimal policy. However, we find that potential gains in targeting sector specific inflation rates rather than the aggregate inflation rate is very sensitive to the shape of the distribution. We show that except for the cases where prices/wages are reoptimized very frequently, the performance of the sectoral rule can be closely approximated by a simple rule that targets aggregate inflation.
