Solid-state imaging device and method of driving the same where three levels of potentials including a negative potential are applied in the transfer gate

摘要

A row scanning unit is configured to change a potential of a transfer signal from a second potential V2 to a third potential V3 prior to driving of a transfer operation for causing a transfer of signal charges from a photodiode to a floating diffusion, by supplying a transfer pulse having a first potential V1. The first potential V1 is a positive potential for turning a transfer transistor into ON state, the second potential V2 is a potential for causing pinning of holes under a gate of the transfer transistor and turning the transfer transistor into OFF state, and the third potential V3 is a potential for not causing the pinning of the holes under the gate of the transfer transistor and turning the transfer transistor into OFF state, the third potential being lower than the first potential and higher than the second potential.
