摘要:

提出了一种新颖的垂直腔面发射激光器(VCSEL)阵列四通道驱动电路的设计和测试结果。该ASIC名为cpVLAD,采用65 nm CMOS技术制造,具有片上电荷泵,每通道数据速率高达10 Gbps。电荷泵的实现是为了解决低温和恶劣辐射环境下VCSEL驱动级的电压裕度问题。测试结果表明,cpVLAD是能够驱动VCSEL的正向电压高达2.8 V,使用1.2 V和2.5 V的电源与功耗为94 mW/通道。

英文摘要:

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.
