Low-Power CMOS Digital Autocorrelator SpectrometerPrototype digital autocorrelator spectrometer circuit designed and built as assembly of few very-large-scale integrated (VLSI) complementary metal oxide/semiconductor (CMOS) circuit chips. Spectrometer contains 128 frequency channels and operates at clock rate of as much as 40 MHz. Total dc power needed is only 6 W. Digital autocorrelator spectrometer consists of four 32-channel autocorrelator chips that collectively produce 128-point spectrum of input signal as computed by use of Fourier transform.
