Design of the Auto Gain Control amplifier based on a resistance modeling of the MOSFET for a distance accuracy of the ToF LiDAR

ToF(Time of Flight) LiDAR detects the target distance by measuring the timing difference of the pulsed laser beam to the target and received signal. The intensity of the received signal varies with a number of factors. The measured timing can be vary depending on the different magnitude of the signals. It is required to control the amplifying gain to ensure accurate distance measurement with wide ...
