摘要
在片内无电源调整电路的条件下,通过电路优化,设计并实现了一种在2.5~5.5V宽电源下稳定工作的锁相环(PLL)。测试结果较好地反映了设计的正确性,并提出了改进意见。
By optimizing the circuit, a mixed-signal phase locked loop (PLL) used in a smart card is designed, which operates properly at 2.5 V to 5.5 V supplies without on-chip voltage regulator. The design is validated by test results. Finally, suggestions are made for further improvement.
