Abstract (in Japanese) (See Japanese page) 
(in English) This paper introduces the pixel front-end (PFE) circuit pitch reduction of SPAD photon count image sensor, which was reported at 2023 Symposium on VLSI Technology and Circuits [8]. A SPAD photon count image sensor with 120-dB High Dynamic Range (HDR) at 3.36 µm-pitch was realized. Conventionally, the SPAD photon count image sensor for realizing HDR has been limited to a PFE circuit pitch of about 10 μm, but the counter circuit in PFE circuit of 8 bits was realized by using a clustered multi-cycle clocked recharging (CMCR) technique with intermediate most-significant-bit readout (MSB-Read). Furthermore, the maximum utilization of the fine logic (22 nm) due to the amplitude limitation reduced the PFE circuit pitch.
