| Title | Design Tool Solutions for Mixed-signal/RF Circuit Design in CMOS Nanometer Technologies |
| Author | *Georges Gielen (Katholieke Universiteit Leuven, Belgium) |
| Abstract | The scaling of CMOS technology into the nanometer era enables the fabrication of highly integrated systems, which increasingly contain analog and/or RF parts. However, scaling into the nanometer era also brings problems of leakage power, increasing variability and degradation, reducing supply voltages and worsening signal integrity conditions, all this in combination with tightening time-to-market constraints. Design methodologies and tools need to be developed to address these problems. This invited paper describes progress in modeling techniques for design and verification of complex integrated systems, in circuit and yield optimization tools for analog/RF circuits, as well as in signal integrity analysis methods such as EMC/EMI analysis. |

| Title | Challenges to Accuracy for the Design of Deep-submicron RF-CMOS Circuits |
| Author | *Sadayuki Yoshitomi (Toshiba Corporation, Japan) |
| Abstract | Increasing complexity, functionality and operating frequency makes RF-CMOS circuit design a tough subject. Efficient use of recent electro-magnetic simulation, which enables the inclusion of many high-frequency effects, and the usage of "more" accurate compact models are the key to overcome this problem. Challenges of these two issues will be shown by the use of real implementation examples. |

| Title | Advanced Tools for Simulation and Design of Oscillators/PLLs |
| Author | Xiaolue Lai, *Jaijeet Roychowdhury (Univ. of Minnesota, United States) |
| Abstract | The lack of fast yet accurate oscillator and PLL simulation methods has constituted a serious bottleneck in mixed-signal, RF and digital design flows. Methods are described that, given differential equations for any oscillator (ie, equivalent to, eg, a SPICE-level circuit), will extract a simple nonlinear phase macromodel. It will be shown how such nonlinear phase macromodels are capable of capturing a variety of important effects, including jitter and phase noise, injection locking, PLL lock and capture phenomena, cycle slipping, etc., while being faster by several orders of magnitude than SPICE-level simulations. It will also be shown how this nonlinear phase macromodel, when applied to large systems of networked biochemical and and nanoelectronic oscillators, correctly predicts spontaneous pattern formation and edge detection. |
