ABSTRACT:
A charge coupled device that includes an output portion having a field effect transistor disposed in the potential well channel to provide a non-destructive read-out of the analog value of a charge pocket located in the portion of such potential well channel beneath the transistor. Drain, source and channel regions of the transistor are disposed transverse to the flow of charge pockets. The conductivity of the channel is modulated as a function of the value of a charge pocket in the potential well beneath the transistor.
