Abstract

Compact mm/submm integrated spectrometers are required for radio-astronomical research, remote monitoring of the Earth atmosphere and environmental monitoring for hazardous materials of chemical and biological origin. Assembled on a multi-chip module the all superconducting integrated spectrometer offers integration of thin film analog components such as a mixer, superconducting local oscillator and an intermediate frequency SQUID amplifier together with superconducting digital circuitry. A Rapid Single Flux Quantum (RSFQ) 128-bit autocorrelator formed by 16-bit autocorrelator and a 112-bit programmable shift register that adjusts the data delay in increments of 16, is used for digitizing of the down converted signals and real-time digital processing. Experimental results showing both operation of components and the way to their successful integration are presented.

ULTRASENSITIVE WIDEBAND INTEGRATED SPECTROMETER FOR CHEMICAL AND BIOLOGICAL AGENT DETECTION

I. V. Vernik

A novel concept of a compact mm/submm integrated spectrometers for environmental monitoring for hazardous materials of chemical and biological origin as well as for remote monitoring of the Earth atmosphere is discussed. The agents will be exactly identified by their unique spectral signatures. The assembled on a multi-chip module, cryocooler-mounted Superconducting Integrated SPectromer (SISP) exploits the superior performance of superconducting Josephson junction technology and unique on-chip integration of analog components, analog-to-digital converter, and digital components. Analog components include a superconductor-insulator-superconductor (SIS) mixer with integrated quasioptical antenna, mm-wave local oscillator, and SQUID amplifier for the down-converted (IF) signals. Upon amplification, the IF signal is digitized using a bandpass delta-sigma modulator, followed by real time processing with rapid single flux quantum (RSFQ) circuitry. Experimental results showing both operation of spectrometer components and the way to their successful integration are presented.

Integrated sub-MM wave receivers

V. P. Koshelets, S. V. Shitov, Andrey M. Baryshev +6 more

The concept of a fully integrated superconducting receiver looks very attractive for sub-mm space astronomy where low weight, power consumption and volume are required. The possibility to integrate on a few chips the different planar components: a SIS mixer, a superconducting local oscillator (LO), an intermediate frequency amplifier followed by superconducting circuits for digitizing and processing of down converted signals, is discussed. A first implementation of a real integrated quasioptical receiver for frequencies up to 500 GHz is described. The one-chip receiver comprises a double dipole antenna, parallel biased SIS array mixer and Josephson Flux Flow Oscillator (FFO) with matching circuits. The results of extensive investigations of the integrated receiver as well as design and investigation of novel superconducting elements are presented.>

All-digital 1-bit RSFQ autocorrelator for radioastronomy applications: design and experimental results

Alexander V. Rylyakov, Stanislav V. Polonsky

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-Mb/s-per-channel output rate. The correlator consists of a digital delay 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/spl times/4 array of accumulators (288 Josephson junctions) fabricated in HYPRES' standard 3.5-/spl mu/m 1000-A/cm/sup 2/ Nb-trilayer process.

A high-speed superconducting digital autocorrelator operating at 20.48 GHz

Steven B. Kaplan, Henrik Engseth

Digital autocorrelators have a number of applications, such as in astronomical observation in the terahertz range, and for spectrum monitoring over wide radiofrequency bands. We have simulated, designed and tested a 16-lag superconducting digital autocorrelator circuits with parallel and also with serial data outputs. By using a novel clock line and a target critical current density of 4.5 kA cm^−2, we have successfully tested this digital circuit up to a clock rate of 20.48 GHz with negligible bit error rates on each lag. Moreover, this autocorrelator design can be expanded with a larger number of lags by tiling chips in a multi-chip module. We also include details of our first multi-chip design.

New design of single-bit all-digital RSFQ autocorrelator

Alexander V. Rylyakov

We present a new design of a Rapid Single-Flux-Quantum (RSFQ) all-digital one-bit autocorrelator for submillimeter spectrometry applications, featuring 4 GHz input signal bandwidth, double oversampling quantizer, and 16 Mbps-per-channel output rate. The delay line of the autocorrelator is based on a circular shift register with XOR gates performing multiplication of the delayed and undelayed single-bit signals at every stage. The multiplication results are accumulated by room-temperature electronics after being prescaled in on-chip binary counters consisting of 10 T flip-flops per stage. We report results of experimental testing of a 16-stage autocorrelator delay line with multiplication and for a linear array of 8 low-power T flip-flop binary counters, all fabricated in HYPRES' standard 3.5 /spl mu/m 1000 A/cm/sup 2/ Nb-trilayer process. We also discuss physical and technical limits of the minimal power dissipation in RSFQ circuits.

SUPERCONDUCTING DIGITAL MULTIPLEXERS FOR SENSOR ARRAYS

Alan M. Kadin, DARREN K. BROCK, Deepnarayan Gupta

Arrays of cryogenic microbolometers and other cryogenic detectors are being developed for infrared imaging. If the signal from each sensor is amplified, multiplexed, and digitized using superconducting electronics, then this data can be efficiently read out to ambient temperature with a minimum of noise and thermal load. HYPRES is developing an integrated system based on SQUID amplifiers, a high-resolution analog-to-digital converter (ADC) based on RSFQ (rapid single flux quantum) logic, and a clocked RSFQ multiplexer. The ADC and SQUIDs have already been demonstrated for other projects, so this paper will focus on new results of a digital multiplexer. Several test circuits have been fabricated using Nb Josephson technology and are about to be tested at T = 4.2 K, with a more complete prototype in preparation.
