  • Publication number: 20090135928
    Abstract: A device, apparatus and method for performing a Fast Fourier Transform (FFT). The Fast Fourier Transform (FFT) processing device includes a coefficient generator, a memory, and an accumulator. The coefficient generator is configured to generate a first set of coefficient values from one or more twiddle factor coefficients. The memory stores the first set of coefficient values. The accumulator receives and accumulates one or more coefficient values from the first set of coefficient values, the accumulator generating one or more output values based on the accumulated one or more coefficient values.

  • Patent number: 5930610
    Abstract: Method for manufacturing a T-gate useful for reducing a gate resistance, improving through-put, and simplifying an MMIC (monolithic microwave integrated circuit) process is disclosed, the method including the steps of depositing a first photoresist layer on a semiconductor substrate and patterning the first photoresist layer so as to expose a predetermined portion of the surface of the substrate; successively forming a seed metal layer and a second photoresist layer on the entire surface inclusive of the exposed substrate and patterning the second photoresist layer so as to define a gate electrode region; plating Au on the seed metal layer on the gate electrode region so as to form a gate electrode; and removing the first and second photoresist layers and the seed metal layer except the gate electrode.
