Abstract
We present the design of a rapid single-flux-quantum all-digital 1-bit autocorrelator for submillimeter spectrometry applications, featuring 4-GHz input signal bandwidth, double oversampling quantizer, and 16-M b/s-per-channel output rate. The correlator consists of a digital dela y line with multiplication and an array of accumulators with parallel readout, We report experimental results for a three-stage delay line ( 294 Josephson junctions) and a 4 x 4 array of accumulators (288 Joseph son junctions) fabricated in HYPRES' standard 3.5-mu m 1000-A/cm(2) Nb -trilayer process.
