2 Using Spectre RF Noise-Aware PLL Methodology to Predict PLL Behavior Accurately • • • • • Introduction Spectre RF Noise-Aware PLL Flow and Non-Linear VCO Modeling Advantages of this flow versus other commercial approaches Experimental results Conclusion September 17, 2007
3 • • • Introduction Phase locked loops are essential blocks in most analog mixedsignal and radio frequency (RF) applications today. Because of the complexity of PLLs, the different time constants involved (two widely-spaced time constants), and the fact that the voltage-controlled oscillator (VCO) frequency often oscillates several order of magnitude faster than the reference frequency, simulating PLLs at a transistor level presents multiple challenges and is extremely time demanding. Cadence SpectreRF Noise-aware PLL flow enables designers to efficiently and accurately predict PLL response using a non-linear model approach to capture the VCO dynamic behavior September 17, 2007
