AUTOMATIC ZEROING CIRCUIT TO COMPENSATE FOR DARK CURRENTS OR THE LIKE

In re application ofPark FrenchFor AUTOMATIC ZEROING CIRCUIT TOCOMPENSATE FOR DARK CURRENTSOR THE LIKEABSTRACT OF THE DISCLOSUREAn automatic zeroing circuit normalizes a detector-measuring apparatus to eliminate relatively steady-state DCerrors that may develop in response to the temperature or othervariable parameter dependency of leakage currents in a transducer,such as dark currents in a photosensitive transistor. Therefore,the outputs from such apparatus are generally insensitive to suchvariables and errors.
