The similarity of data is important in the fields of pattern matching and data comparison. In this paper, the authors propose a new hamming distance detector using a neuron CMOS A/D converter with two output terminals. The detector outputs the signals which are corresponding to the hamming distance between two input data immediately. The FPD method is applied to design the ratio of each input capacitance of the proposed detector. To verify the behavior of the proposed detector, the computer simulations were carried out by LTSpice.
