论文摘要
我们提出了一种新颖的设计和4通道驱动器的测试结果，用于一系列垂直腔表面发射激光器（VCSEL）。该ASIC被称为CPVLAD，并在65 nm CMOS技术中制造，具有芯片电荷泵，并且每个通道的数据速率最高为10 Gbps。实施电荷泵是为了解决低温和恶劣辐射环境下应用程序中VCSEL驾驶阶段电压率的问题。测试结果表明，CPVLAD能够使用1.2 V和2.5 V电源以94 MW/Channel的电源驱动高达2.8 V的VCSEL。
We present a novel design and the test results of a 4-channel driver for an array of Vertical-Cavity Surface-Emitting Lasers (VCSELs). This ASIC, named cpVLAD and fabricated in a 65 nm CMOS technology, has on-chip charge pumps and is for data rates up to 10 Gbps per channel. The charge pumps are implemented to address the issue of voltage margin of the VCSEL driving stage in the applications under low temperature and harsh radiation environment. Test results indicate that cpVLAD is capable of driving VCSELs with forward voltages of up to 2.8 V using 1.2 V and 2.5 V power supplies with a power consumption of 94 mW/channel.
