摘 要

滤波器作为一款基本的电路元件，其用途十分广泛，在诸多领域发挥着重要作用。电子产业经过这多年的积累与发展，集成电路已经成为电子线路设计的主流。现如今许多集成电路的设计都已经离不开滤波器这一角色。尤其是在音频、射频等信号传输与处理领域，滤波器的身影更是随处可见。针对滤波器的各项研究已经相对而言比较成熟。滤波器种类繁多，对使用场合极为敏感，根据不同的用途可以将滤波器分为不同的类型。本次论文单从高通滤波器这一点出发，着重分析其构造原理以及探讨怎样设计一款可以满足实际需求的高通滤波器。高通滤波器的作用虽然很好理解，但是其设计过程并不简单。在不同的应用场合下往往有着不同的限制，由于客观现实的局限性，因此对滤波器的设计要求也就显得十分苛刻。面对实际中的各种约束，怎样利用现有的条件设计一款合适的高通滤波器还是很有值得深入研究的。根据现代滤波器设计理论，绝大部分滤波器均可以使用巴特沃斯滤波器、切比雪夫滤波器、贝塞尔滤波器等设计理论来构造。本次论文将由浅入深，探讨怎样结合这些理论来完成设计需求。除此之外，还会借用ADS软件（Advanced Design System）进行滤波器仿真，以此来验证设计是否正确合理。

Abstract

Filter as a basic circuit element, its application is very extensive, plays an important role in many fields. Electronics industry after the many years of accumulation and development, the integrated circuit has become the mainstream of electronic circuit design. Nowadays many integrated circuit design has been inseparable from the filter that part. Especially in the field of audio, such as RF signal transmission and processing, the figure of filter is everywhere. In view of the filter in all kinds of research has been relatively mature. There are many different kinds of filter, the use of occasions extremely sensitive, according to the different USES of filter can be divided into different kinds. Single from high-pass filter to this point, this paper analyzed the construction principle and discussed how to design a high-pass filter can meet the practical requirements. The effect of high-pass filter is easy to understand, but its design process is not simple. Tend to have different in different application situation, due to the limitation of the objective reality, so the design of filter is also very demanding. Facing the actual in various constraints, how to take advantage of existing conditions to design a suitable high-pass filter are worthy of further study. According to the theory of modern filter design, all can be used most of the filter, butterworth filter, chebyshev filter, such as Bessel filter design theory to construct. This paper will build incrementally, and discusses how to combine the theory to complete the design requirements. In addition, still can use ADS software (Advanced Design System) filter simulation, in order to validate Design is correct and reasonable.

第1章 ADS软件

1.1 ADS软件基本介绍

ADS软件，全称Advanced Design System，即高级设计系统。此软件由国际著名的安捷伦科技公司自主研发，因其强大的功能在工业设计领域具有着重大作用。ADS作为一款先进的自动化设计软件，以其丰富的模板支持和高效准确的仿真能力(尤其在射频微波等领域)，得到了广大IC设计工作者的支持^[1]。

ADS是高频设计领域里的标杆，其作用与价值是相当深远的。ADS软件支持系统和射频设计师开发过程中所有类型的射频设计，不管简单还是复杂的ADS都囊括其中，从射频微波模块到用于通信和航空航天的MMIC，ADS都有涉及。
