The paper presents a fully integrated multiphase output low-jitter CMOS phase-locked loop for 1.25 Gb/s to 6.25Gb/s wireline SerDes transmitter clocking. The self-biased bandwidth technology with simplified structure is applied to reduce the sensitivity to process variations. A differential charge pump which has property of low mismatch is proposed. The self-biased technology is used to make the bandwidth...
Generally the conventional bearingless switched reluctance motors (BSRMs) need to work with magnetic bearings to realize the active control of five-Degrees Of Freedom (5-DOF) of the rotating part. However, this kind of structure increases the total cost and reduces overall efficiency of the 5-DOF suspension system. Moreover, the axial length of the rotor is greatly increased which limits the rotor...
