A low power, small area front collision avoidance circuit using Light Detection and Ranging technology is presented in this paper. The proposed system would help detect and avoid the objects which would otherwise collide with an autonomous vehicle. After the front sensor detects stopped or slowed down vehicles, all sensors will turn on and make decisions based on the system's algorithm calculations. The system is implemented in CMOS 90nm technology. The power consumption of the system is 1.424mW and uses a 1.2V power supply. 4ns resolution front end sensors and 1ns resolution side sensors are used to compare the target distance with a safety standard. The processing time for making decisions is 889.5ns when the car is traveling 45mph which includes the 800ns sensor detection time.
