DIGITAL PIXEL IMAGER WITH DUAL BLOOM STORAGE CAPACITORS

An integration capacitor network for connection to a photo-current source includes: an input; a first path connected between the input and a reset voltage, the first path including a first integration capacitor and a first cascode transistor, the first cascode transistor coupled between the input and the first integration capacitor; and a second path connected between the input and the reset voltage, the second path including a second integration capacitor and a second cascode transistor, the second cascode transistor coupled between the input and the second integration capacitor. Gates of the first and second cascode transistors are connected to a reference voltage and charge is accumulated on the first integration capacitor until a voltage on the first integration capacitor exceeds the reference voltage and then charge is accumulated on the second integration capacitor.
