Abstract
An open-loop phase-locking scheme is proposed. It uses an open-loop control mode to avoid the problem of weak feedback in a phase-locked loop in the case that the output frequency is much higher than that of the reference. A synchronous circuit is designed with this scheme, and is simulated with the transistor models of a 0.18 μm technology. The phase error is 59.13/14.26 ps peak-to-peak/rms when the frequency of the circuit output is 270 MHz.
