用于高频的新颖开关电容积分器

本文研究了用于开关电容(SC)滤波器的离散积分器,所推荐的积分器是由无耗离散积分器(LDI)和双线性离散积分器的最佳线性结合而成,因此,称之为组合离散积分器(CDI)。由于这个积分器使正常转折频率增加一倍,并使高频离散积分器误差减少到最低限度,所以它对高频应用是理想的。文中给出了组合离散积分器的几种SC实现,并且还给出了以组合离散积分器为基础,模拟一般一阶和二阶的模拟滤波器单元的SC电路。     

中国"以电子政务拉动信息产业发展"政策的再评估

电子政务是中国信息化战略的重中之重，但其实际发展与预期间存在着明显差距。本文以中国“以电子政务拉动信息产业发展”政策为研究重点，把这一政策放在中国信息化历史中加以考察，分析中国信息化新阶段ICT市场的新变化和新挑战，针对电子政务实践与预期间的差距，对该政策提出我们的看法。

What Prompts the People＇s Bank of China to Change Its Monetary Policy Stance？ Evidence from a Discrete Choice Model

In the present paper, we model the policy stance of the People＇s Bank of China （PBC） as a latent variable, and the discrete changes in the reserve requirement ratio, policy interest rates, and the scale of open market operations are taken as signals of movement of this latent variable. We run a discrete choice regression that relates these observed indicators of policy stance to major trends of macroeconomic and financial developments, which are represented by common factors extracted from a large number of variables. The predicted value of the estimated model can then be interpreted as the implicit policy stance of the PBC. In a second step, we estimate how much of the variation in the PBC＇ s implicit stance can be explained by measures of its policy objectives on inflation, growth and financial stability. We find that deviations of CPI inflation from an implicit target and deviations of broad money growth from the announced targets, but not output gaps, figure significantly in the PBC＇s policy changes.
