Abstract

This paper classifies and compares the commonly used indirect TOF implementation devices. Device types are mainly classified into PPD (pinned photodiode) and CAPD (Current Assisted Photonic Demodulator). Two kinds of devices’ demodulation contrast is studied theoretically and simulated by TCAD. According to theoretical analysis, the structure and timing of PPD devices are improved. The simulation results of TCAD show that the demodulation contrast of the device can be improved greatly. The improved PPD structure can achieve 80% demodulation contrast at 100MHz demodulation frequency.
