ABSTRACT:
N charge signals B.sub.N-1 . . . B.sub.0 in N channels represent an N digit binary code. The charge signal B.sub.N-1 representing the most significant binary digit is sensed to produce an output charge signal G.sub.N-1 representing the most significant Gray code digit. The N-1 remaining charge signals are processed by, in each case, adding a charge signal representing one binary digit B.sub.j to a charge signal B.sub.j-1 representing the binary digit of next lower significance in EXCLUSIVE OR fashion to obtain the Gray code digit G.sub.j-1.
