Direct Time-of-Flight (D-TOF) becomes more and more important for many functions in smartphones, such as proximity detection, auto focus assist, gesture or presence detection as this technology enables compact devices with low power consumption.
This presentation will give insights in the ams D-TOF technology for mobile devices.
The module is based on a 55nmHV technology and contains sensor, processor and laser driver on a monolithic die, as well as a multi-mesa VCSEL within the module. A custom developed Single-Photon-Avalanche-Diode and the corresponding sensor array enable multi-zone and multi-object detection using histogram based data collection. The availability of the raw histogram data allows multi-object detection and makes the system insensitive to crosstalk and smudge on the sensor. Distance resolution in the mm-range is achieved by using a free running ring oscillator based Time-to-Digital converter with digital calibration. On the emitter side, the on-chip VCSEL driver pulses a multi-emitter VCSEL with high optical peak power and sub-ns pulse width which results in an improved SNR and allows distinction of multiple objects at close distance to each other within the observed scene. The complete system is class 1 eye safe.
