A high-accuracy position-sensitive photodetector (PSD) for integrated sensor systems is presented. A 2-axis PSD composed of a dense array of vertical phototransistors and two arrays of polysilicon resistors was implemented using standard CMOS technology. Test results show better resolution and linearity as compared to a high-quality conventional PSD.
