A completely integrated thirty-two-point chirp Z transform [CCD IC realisation]

A monolithic 32-point DFT using the chirp Z transform (CZT) algorithm has been designed and fabricated using an n-channel two-level polysilicon coplanar electrode process. The detailed design and operation of this first fully integrated CCD chirp Z transform are discussed, and some spectral analysis applications for a CCD CZT are described.
