MPQ3910A REFERENCE DESIGN - HIGH VOLTAGE BOOST FOR APD IN LIDAR APPLICATIONSAutonomous vehicles have been a hot topic for some time, but now they are staring to become a reality. To enable high degrees of autonomy, vehicles are using combined methods (cameras, radar, and LiDAR) to detect surroundings. LiDAR is a ranged device. It functions similarly to radar, but uses light waves instead of RF waves. A laser diode emits light pulses, and an advanced photodiode (APD) sens...
