Abstract
It is frequently desirable to establish the level of charge in the first potential well of a CCD in accordance with an external electrical signal. Thermal noise associated with the output resistance of the external source gives rise to uncertainty in this charge level. The use of a floating diffused region as an intermediate receptacle for the charge introduced permits a substantial reduction in the magnitude of this uncertainty.
