|Title:||Design and Circuit Analysis of Quasi-one Junction SQUID Comparators for Low Temperature Detector Array Read-out||Authors:||Bozbey, A.
Quasi-one junction SQUID comparator
|Issue Date:||2011||Publisher:||Springer||Abstract:||In this study, we report on our simulation and experimental results for quasi-one junction SQUIDs (QOS) comparator targeted to be used in the front-end of the detector read-out circuits. The QOS is used as a 1-bit quantizer in the front-end of the read-out circuit. Their performance and reliability is very much depending on the circuit parameters of the QOSs. The main design parameters are the threshold level, gray zone width, and the chip-to-chip reproducibility over different fabrication batches. For some special applications, such as detector readout, the overall power consumption needs to be sufficient small. We measured threshold and gray zone counting each individual switching event for various bias and input current values and for different QOS designs. In addition, circuit simulations including thermal noise are used to explain the observed circuit behavior and to optimize design parameters.||URI:||https://doi.org/10.1007/s10948-010-0865-y
