Summary :

This paper presents a discrete Fourier analyzer using analog VLSI technology. An analog current-mode technique is employed for implementing it by a regular array structure based on the straight-forward discrete Fourier transform (DFT) algorithm. The basic components are 1-dimensional (1-D) analog current-mode multiplier array for fixed coefficient multiplication, two-dimensional (2-D) analog switch array and wired summations. The proposed scheme can process speedily N-point DFT in a time proportional to N. Possibility of the realization of the analog DFT VLSI based on 1 µm technology is discussed from the viewpoints of precision, speed, area, and power dissipation. In the case of 1024-point DFT, the standard deviation of the total error is estimated to be about 2%, the latency, or processing time is about 110 µs, and the signal sample rate based on a pipeline manner is about 4.7 MHz. A prototype MOS integrated circuit of the 16-point multiplier array has been implemented and a typical operation using the multiplier array has been confirmed.
