Abstract
A charge transfer analog-to-digital converter is provided with means to establish the potential across a large storage well at a comparator threshold voltage at the initiation of a cycle. Charge transfer circuitry is also provided for transferring, into the large potential well, charge packets of size dependent only upon the value of a charge packet capacitance and a scaling voltage. Parasitic capacitance effects are essentially eliminated.
