A switched-capacitor filter which occured abroad these years is a kind of all-integrated active filter. It's advantages are high precision, low sensitsvity etc. This paper mainly discusses how to use the Loss-Less Discrete Integrator (LDI) Transformation to realize SCF.For Optimal calculation,we derive the regular design formula of SCF and avoid using the Mason formula which may lead to complication. By means of the given formula, the coefficient-match principle and the Newton method, the inherent errors of SCF rosulting from the use of the LDI Transformation are rooted out.The calculation steps of the optimal design of SCF and an example are given in the paper.The Optimal design method given in this paper can make the cut-off freguency close to the half of the switch freguency with the necessary design precision of the filter.

开关电容滤波器(Switched-capacitor filter简称SCF)是国外近几年出现的一种全集成化有源滤波器。它具有精度高、灵敏度低等一系列优点。本文将重点讨论如何运用无损离散积分器(Loss-Less Discrete Integrator简称LDI)映射变换来实现开关电容滤波。 为了进行优化计算,文中避免运用Mason公式的烦琐推导,将按本文给出的规律,直接写出这种SCF的设计公式。按此公式,采用系数匹配法优化原理和牛顿法,可消除运用LDI映射实现SCF所导致的误差。 本文给出了SCF优化设计全过程的具体步骤和算例。 按本文给出的优化设计方法,在满足滤波设计要求的前提下,可使SCF的通带截止频率接近开关频率的二分之一。

The optical system of an extinction instrument for measuring particle dia- meters is considerably improved. A xenon-arc lamp with a pole to pole distance of 1mm is used as the point light source. It is shown that, by using standard styrene latex for the calibration of the instrument, the inherent error of the optical system is found to be less than 0.6 percent while that of the original optical system is more than 1 percent. The problem of rationally selecting the light wavelengthes is discussed. When wavelengthes of 0.4-0.8μm are used, the optimum range for droplet diameter measurement of a monodisper-sion is 0.08-2.4μm.
