用于ATLAS像素探测器中光学数据传输的抗辐射ASIC

Radiation-hard ASICs for optical data transmission in the ATLAS pixel detector

K. K. Gan

摘要:

我们已经开发了两个辐射硬ASIC的ATLAS像素探测器中的光数据传输在欧洲核子研究中心的LHC:垂直腔面发射激光器(VCSEL)二极管的驱动芯片,用于80 Mbit/s的数据传输从检测器,和一个双相标记解码器芯片恢复的控制数据和40 MHz的时钟接收光的PIN二极管。我们已经成功地实现了0.25毫米CMOS技术的ASIC使用封闭布局晶体管和保护环增加辐射硬度。我们给出了最终设计电路的结果,以及用24 GeV质子在62 Mrad(2.3 x 10^15 p/cm^2)下进行辐照研究的结果。

英文摘要:

We have developed two radiation-hard ASICs for optical data transmission in the ATLAS pixel detector at the LHC at CERN: a driver chip for a Vertical Cavity Surface Emitting Laser (VCSEL) diode for 80 Mbit/s data transmission from the detector, and a Bi-Phase Mark decoder chip to recover the control data and 40 MHz clock received optically by a PIN diode. We have successfully implemented both ASICs in 0.25 mm CMOS technology using enclosed layout transistors and guard rings for increased radiation hardness. We present results from circuits of final design and from irradiation studies with 24 GeV protons up to 62 Mrad (2.3 x 10^15 p/cm^2).
