Abstract
The design of an integrated 40A pulsed driver for ToF LiDAR in GaN-on-SOI technology is presented. The produced laser current, generated by a resonant circuit, can achieve sub-nanosecond rise time. The design aims to optimally exploit GaN technology, mitigating source bounce effects and compensating the lack of complementary devices, while preserving reliability. The integration process minimizes parasitics via wafer-level-chip-scale packaging (WLCSP), enhancing the performance of the driver.
