Paper: A 1.9mW Portable ADPLL-based Frequency Synthesizer for High Speed Clock Generation
CONCLUSIONS:
In this paper, a 1.9mW portable ADPLL-based frequency synthesizer with wide frequency range, low jitter, and short lock cycle is proposed.
A DCO with features of wide frequency range, and low power consumption is proposed. By using the modified DCDEs, the DCO also has better linearity and PVT variation immunity than the conventional DCO. In addition, a dualmode one-cycle PFD is also presented to reduce the lock cycle time.
In conclusion, with such specifications, the proposed ADPLL-based frequency synthesizer is suitable for high speed clock generation in SoC applications. |
