ABSTRACT:
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.
