Consumer Electronics GaN Applications: Time of Flight (ToF)/Lidar

Time of Flight (ToF)/Lidar for Consumer Electronics
GaN Enables Advanced Autonomy: See Farther, Faster, Better

As the cost of time-of-flight/lidar systems continues to fall, the technology is finding its way into an increasing array of consumer applications. Smartphones are beginning to use lidar for computational photography and augmented reality functions. Robot vacuums are increasingly using lidar for navigation and obstacle avoidance. Lidar is also becoming the preferred technology for service robots and cobots.

GaN FETs and ICs create the high-current optical pulses with extremely short pulse widths required for higher resolution, longer range, and safe ToF/Lidar systems. These benefits along with the extremely small size and low cost, make GaN the ideal solution helping all ranges of lidar systems see farther, faster, and better.
