Abstract
A Gray code counter includes a holding circuit, first and second conversin circuit and an operation circuit. The holding circuit stores gray code signals and outputs the stored gray code signals in response to a clock signal. The first conversion circuit receives the gray code signals from the holding circuit and converts the received gray code signals into first binary code signals. The operation circuit applies a logical operation to the first binary code signals so as to generate second binary code signals. The second conversion circuit receives the second binary code signals and converts the received second binary code signals into the gray code signals. The second conversion circuit outputs the gray code signals to the holding circuit.
