| Abstract: | A novel simulation algorithm of charge pump PLL is proposed. The transition event of the oscillation signal is estimated by the simulated data before and after the event time. At the same time the simulation step is adjusted exponentially, which greatly improve the simulation speed and accuracy. A PLL simulator is programmed using C language, and a 250 MHz charge pump PLL is simulated. The simulation speed and accuracy is much better than that of Cadence Spectre. |
