基于FPTA的动态可重构模拟电路研究

Research on Dynamic and Reconfigurable Analog Circuits Based on FPTA

阐述了基于FPTA的模拟可进化电路的设计方法,分析了FPTA的结构,介绍了进化设计所使用的遗传算法,分析了使用PSpice软件建立的仿真模型,并通过VB程序实现算法并对演化过程进行控制。以4位数模转换电路(DAC)为例,通过对4个FPTA细胞组成的电路结构进行进化实验,结果表明4个FPTA细胞完全能够进化得到4位DAC。

The method for evolving analog circuits based on FPTA is presented, the architecture of FPTA is analysed and the evolutionary algorithm is introduced. In extrinsic evolution, circuits are converted into a model simulated by PSpice. The process of evolving analog circuits is controlled by VB and algorithm is realized also by it. The experiment of 4-bit DAC shows that the function can be achieved using four FPTA cells.
