摘要 A new ROMless twiddle factor generator for radix-2 1024-point FFT is proposed.It consists of several simple logic units and each of them synthesizes some data,which will be used to compose the twiddle factors.The power analysis with Synopsys Power Compiler shows that it consumes about 2mW with TSMC 0.25μm CMOS process at 50MHz.This twiddle factor generator is designed for the low power applications,especially for the mobile communications and other portable devices... 设计了一个新的无存储器的基 - 2 1 0 2 4点 FFT旋转因子产生电路 .这个旋转因子产生电路用若干逻辑模块来产生数据 ,然后用这些数据合成所需要的旋转因子 .用 Synopsys Power Compiler进行功耗分析表明 ,用 TSMC0 .2 5 μm CMOS工艺综合出来的电路在 5 0 MHz时的功耗为 2 m W.这种旋转因子产生电路非常适合用于低功耗的设计中 ,尤其是移动通信和其他手持设备中 .
