A low power CMOS correlator

A full custom, 25 MHz, 1.6 mu m CMOS correlator chip is presented. The 5.15 mm by 4.23 mm chip performs either autocorrelation or crosscorrelation, consuming less than 10 mW per channel. The correlator, designed for a space borne spectrometer, contains 32 channels and is cascadable. The correlator was designed to Mil Spec, 3 sigma Worst Case Speed parameters.<<ETX>>
