An improved gain compression device is disclosed, especially for use in charge-coupled devices. The device is preferably constructed on a semiconductor substrate and includes a first potential well in close proximity to a mobile charge packet generation region. A second potential well is separated from the generation region by a diffusion region. The first potential well becomes saturated and drains to a drain region while the second potential well continues to fill.

Gain compression photodetector array

A gain compression method and apparatus which is especially suitable for charge coupled devices is disclosed. A mobile charge packet generation area is provided with an adjacent overflow barrier. The overflow barrier is adjacent an N+ diffusion region which provides parasitic capacitance to the overflow barrier. The diffusion region adjusts the potential of the overflow barrier as greater amounts of charge overflow the barrier.
