چکیده

A microwave superconducting quantum interference device multiplexer has been optimized for reading out large arrays of transition-edge sensor (TES) bolometers. We present the scalable cryogenic chip design that may be used to construct an 1820-channel 4–8 GHz rf band. The key metrics yield, sensitivity, and crosstalk are determined through measurements 455 readout channels, which span 4–5 GHz. median white-noise level is 45 pA/Hz, evaluated at 2 Hz, with a 1/f knee ≤ 20 mHz after common-mode subtraction. decreases sensitivity TES bolometer detection cosmic background 150 by only 3%. measured between any channel pair 0.3%.

Adjustable 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...

A microwave resistive squid for noise thermometry

2014 A SQUID magnetometer has been shown to work at 10 GHz with a significant enhancement of signal-to-noise over 30 MHz devices. This article describes how such enhancement could lead to faster determinations of absolute temperature using a resistive SQUID, i. e., a noise thermometer. A prototype 10 GHz resistive SQUID is described and its performance evaluated. The feasibility of using a 10 G...

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 ...

A Regularly Modularized Multiplexer-based Full Adder for Arithmetic Applications

In this paper, we propose a novel multiplexer-based full adder design, denoted as MUXFA, by using regular modules for arithmetic applications. The MUXFA full adder is composed of three identical modules, in which each module separately operates for XOR-XNOR function, sum function, and carry function. The structure of the multiplexer-based full adder can be easily constructed by merely a single ...
