    摘要: A method and apparatus for performing division which calculates a quotient from a dividend and a divisor by using recursive subtraction operations without using carry propagation for each subtraction operation. The apparatus contains a circuit (16) for generating a plurality of quotient digits from the divisor and the dividend. The apparatus also contains a circuit (18, 20) for generating the quotient from the quotient digits.

    摘要: A buried channel to surface channel charge coupled device includes a blocking gate and a transfer gate situated between a buried channel gate and a surface gate for transferring electron charge from the buried channel to the surface channel. The blocking gate is located over the buried channel and the transfer gate straddles the buried and surface channels. The blocking gate serves to overcome the potential barrier associated with buried to surface channel transfers.
