Abstract:	The simplest 2T1C sensing circuit has high aperture ratio in pixel, while it suffers from a severe error owing to the voltage drop on scan bus. In order to solve this issue, a dual-scanning active amplifier sensing circuit is proposed, which can correct the sensing error from 38.5% to 5.7%.
