| Abstract | In this paper, a new method to reduce the quantization error in time measurement technique is proposed for a SPAD readout circuit. Initially, we developed a novel readout method to enhance the readout dynamic range of pixel based on a single photon avalanche photodiode by using a double readout technique based on time and amplitude measurements without decreasing the fill factor. In this paper we describe the contribution of the proposed method applied to time measurement technique in reducing the quantization error simply by using a multiple time resolution. It is important to notice that the main advantage of this method is the ability to apply it to all Active Pixel Sensor (APS). © 2016 IEEE. |
