Abstract
In this paper a multiple strip photo mixing
demodulator fabricated on high resistivity silicon is described.
The performance such as DC characteristics, demodulation
contrast and non-linearity problem of a test sample are
simulated and experimentally estimated. The experimental
results exhibit a good DC charge separation and good dynamic
demodulation capabilities up to 30MHz. The influence of
modulation frequency and voltage on this device is also
discussed. This test device corresponds to the first step
towards incorporating a high resolution Time of Flight (TOF)
based 3D image sensor.
