Abstract
A pixel includes an integration capacitor coupled between a system voltage and a pump voltage source and having a first side and a second side. The pixel can be operated to have a large full well by: storing charge from a photo-current source in the integration capacitor; reading out the integration capacitor; resetting the integration capacitor by connecting the capacitor to a column line through a select transistor; while resetting, setting the pump voltage source to the system voltage; and after resetting, setting the pump voltage to ground to create a negative voltage between the integration capacitor and column line.
