Abstract :
A decision circuit with a function of detecting the phase difference between the input data signal and the clock signal is presented. The novel circuit technology has been used for the phase detectors. A linear and wide-rage phase detection was achieved as well as a wide phase margin of 288/spl deg/ and a small decision ambiguity of 27 mVPP up to 10 Gb/s.
