A practical fast Fourier transform (FFT) processor can contain several millions of gates, so effective design techniques usually are required in order to guarantee high-speed products. A look-up table (LUT) methodology is developed and demonstrated on variable length (128-1024 point), variable bit-precision (6-12 b) FFT with uniform bit truncation and optimum bit truncation for wideband digital receiver in radar applications. The FFT processors are designed using a standard 130 nanometer CMOS… CONTINUE READING
