ABSTRACT:
An analog-to-digital (A/D) converter using a charge-coupled device (CCD) for converting analog data to digital data, the CCD including a plurality of gates with potential wells, the number of gates corresponding to a number of bits of the digital data, and a size of each potential well corresponding to a given significant bit and being one-half the size of the potential well corresponding to the next most significant bit. The charges of an input analog signal are transmitted to respective potential wells. A plurality of driving circuits apply a voltage to the respective potential wells and output the charges stored in the respective potential wells as digital data.
