Abstract
This article presents a 320 × 240 indirect time-of-
flight (iToF) CMOS image sensor (CIS) with on-chip motion arti-
fact suppression and background light cancelling (BGLC). The
proposed iToF CIS uses a backside-illuminated trident pinned
photodiode (PPD) that assists charge transfer with a built-in
lateral electric field for enhanced depth accuracy. To overcome
the limitation of the conventional iToF CIS that exhibits motion
artifact, we propose a pseudo-four-tap (P4-tap) demodulation
method with
