Abstract

This paper introduces a concept of analog-to-digital conversion for very high-speed applications. Like the time-interleaving conversion, this method uses different conventional ADCs (channels), which work in parallel, but the approach is different. The basic principle is close to techniques used in signal processing, such as the discrete Fourier transform (DFT) and sub-band coding. Because of its low sensitivity to sampling-clock jitter; this technique can achieve a 6 bit effective accuracy up to the Nyquist frequency.
