ABSTRACT:
A non-destructive sensing of mobile charge in charge transfer devices or other MOS devices is accomplished by the use of a circuit utilizing two operational amplifiers. One operational amplifier is employed as an inverting amplifier responsive to one input signal, and the other operational amplifier is employed as a summing amplifier responsive both to a second input signal and to the output signal from the first operational amplifier. The electrodes of the MOS device being sensed, as well as capacitors in the sensing circuit, are precharged to given voltage levels before the actual sensing occurs.
