Abstract
A phase detector for generating a phase difference signal indicative of a phase difference between a first bi-level signal of frequency Fand a second bi-level signal of frequency Fis proposed. The phase detector may include first and second detector inputs, first and second flip-flops, a NAND gate, and a first and second overphase detection units. An output of the first overphase detection unit may be connected to a direct input of the second flip-flop and may be arranged to output the level '1' in response to F≦Fand the level '0' in response to F>F. An output of the second overphase detection unit may be connected to a direct input of the first flip-flop and may be arranged to output the level “1” in response to F≦Fand the level “0” in response to F>F
