Abstract :
In this paper, an analog optical-comparator-based VLSI velocity and direction motion sensor is newly proposed. Without using complicated calculation as performed by DSP, the proposed chip is attractive due to the fact that the proposed method is low-cost, and easier to be implemented. The chip area is 1.47 × 1.49 mm2. The detecting speed range is from 0.009 to 1.5 m/s. All the functions and performance of the proposed chip are successfully tested and proven through measurements. The proposed chip is suitable for devices of detecting the speed and direction of objects.
