tivity curve [curve (i) of Fig. 2], the self-oscillation frequency is higher while the frequency range is approximately the same. 2) Injection-Locked Frequency Divider: A different ap- proach can be used to design a divider that operates at an even higher frequency than the previous version...
Section 3 introduces the design of the clock feedthrough suppressed charge pump with additional bias current branches, the VCO with a wide tuning range, and the symmetrical CML divider, respectively. Section 4 presents the experimental results obtained from the proposed PLL. Finally, Section 5 ...
