摘　　要：模拟集成电路代替传统的分立元件电路,省去许多电阻、电容的接线,具有调节方便,集成度高的鲜明优势。本文介绍了一种最新推出的模拟集成电路—在系统可编程模拟电路(简称ispPAC)的功能及特点,然后以ispPAC10为例设计了一个二阶带通滤波器,并给出了其仿真的幅频特性曲线和相频特性曲线,实验结果基本达到了设计指标。本器件的开发可以在软件对话框窗口中直接更改参数,滤波器的频率在10kHz到100kHz的范围内有近120种不同的选择,精度为3%。It has distinct advantage to replace conventional discrete element circuits by analog integrate circuits. This paper introduced the functions and characteristics of a latest announced analog integrate circuit-In System Programmability Programmable Analog Circuits （ispPAC） .The design of a two order- band- pass filter is used as an example, and it＇ s designing process and simulation result are introduced, and the Amplitude - frequency Curve and Phase - frequency Curve are given too. The experiment result basically achieved the designing index. We can change the parameters directly in the software dialog box when we exploit this chip. The frequency of filter has 120 different choices ranging from 10KHz to 100KHz,with a precision of 3%.
