Single SQUID Multiplexer for Arrays of Voltage-biased Superconducting Bolometers
We describe a frequency domain superconducting quantum interference device (SQUID) multiplexer which monitors a row of low-temperature sensors simultaneously with a single SQUID. Each sensor is ac biased with a unique frequency and all the sensor currents are added in a superconducting summing loop. A single SQUID measures the current in the summing loop, and the individual signals are lock-in ...
متن کاملAdjustable SQUID-resonator direct coupling in microwave SQUID multiplexer for TES microcalorimeter array
We have succeeded in the first demonstration of a simple and accurate resonator-superconducting quantum interference device (SQUID) coupling for microwave SQUID multiplexers. A simple theory shows our direct coupling with adjustable fractional inductance in the SQUID loop can decrease the deviation of resonance frequencies from designed values in contrast to a conventional inductive coupling. O...
متن کاملA spread spectrum network analyser
The paper describes the realisation of a Spread Spectrum Network Analyser using appropriate software to control a PC interface card, like a soundcard. The software generates a digitised time waveform consisting of a Spread Spectrum signal containing a number of equal amplitude spectral components. The interface card converts this waveform to an analogue signal, which is then passed through the ...
متن کاملSpread-Spectrum Computation
We observe that existing methods for failure-tolerance are inefficient in their use of time, storage and computational resources. We aim to harness the power of idle desktop computers for data-parallel computations, which are particularly sensitive to failure, and propose spreadspectrum computation as a suite of techniques to mitigate failures in an internet-scale distributed system. Spread-spe...
متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
