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

摘要： 我们为欧洲核子研究中心（CERN）大型强子对撞机（LHC）的ATLAS像素探测器中的光学数据传输开发了两种抗辐射ASIC：一种是用于垂直腔面发射激光器（VCSEL）二极管的驱动芯片，用于从探测器以80 Mbit/s的数据传输，另一种是双相标记解码器芯片，用于恢复通过PIN二极管光学接收的控制数据和40 MHz时钟。 我们成功地使用封闭版图晶体管和防护环在0.25 mm CMOS技术中实现了这两种ASIC。 我们展示了最终设计电路的结果以及使用24 GeV质子进行的辐照研究结果，最大辐照剂量达到62 Mrad（2.3 x 10^15 p/cm^2）。 显示英文摘要

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).
