摘要:

我们报告的低噪声,低功耗,混合模拟-数字SIRIUS ASIC的LAD和WFM X射线仪器的LOFT的发展和表征。我们开发的ASIC正在读取大面积硅漂移探测器(SDD)。ASIC设计的基础是对噪声(ENC为17 e-,在6 keV下实现LAD上200 eV FWHM的能量分辨率)和功耗(每通道650 μW)的严格要求。这些SIRIUS ASIC的开发是为了匹配SDD探测器的特性:将制造16个通道的ASIC,适用于LAD(970微米间距)和64个通道的WFM(145微米间距)。ASIC采用TSMC的180 nm混合工艺开发。

英文摘要:

We report on the development and characterization of the low-noise, low power, mixed analog-digital SIRIUS ASICs for both the LAD and WFM X-ray instruments of LOFT. The ASICs we developed are reading out large area silicon drift detectors (SDD). Stringent requirements in terms of noise (ENC of 17 e- to achieve an energy resolution on the LAD of 200 eV FWHM at 6 keV) and power consumption (650 μW per channel) were basis for the ASICs design. These SIRIUS ASICs are developed to match SDD detectors characteristics: 16 channels ASICs adapted for the LAD (970 microns pitch) and 64 channels for the WFM (145 microns pitch) will be fabricated. The ASICs were developed with the 180nm mixed technology of TSMC.
