This paper presents a pixel array position sensitive detector (PSD) with analog winner-take-all (WTA) blocks. The pixels are divided into M-number of sub-groups and a WTA is assigned to each sub-group. The winner pixel of entire pixels is obtained from the sum of the sub-group's winner addresses. Detailed noise analysis shows that there is an optimal number of sub-groups for improved noise immunity.
