For MOS devices, a new relationship for 1/f noise is given which allows intuitive insight when comparing technologies. Both bipolar and MOS transistors show agreement to a number fluctuation model for noise mechanisms. A factor of 2 lower 1/f noise is determined for the PNP in comparison to NPN transistors. For this technology generation, bipolar transistors indicate an order of magnitude lower noise level when compared to MOSFETs under similar drive currents and effective area conditions. Finally, we discuss generation recombination noise, which can be observed in some of the devices.","PeriodicalId":101717,"journal":{"name":"Proceedings of the IEEE 2001 Custom Integrated Circuits Conference (Cat.

The starting point is a high-level specification using the general-purpose programming language C++. By making use of a set of class libraries developed internally at IMEC, architectural trade-offs can be easily explored. The open nature of a C++ based design environment supports the re-use of previously designed building blocks and allows designers to extend the typically supported design-flow eliminating the need for manual generation and correction of synthesis and verification scripts. Automated HDL (Hardware Description Language) code generation from the C++ descriptions creates the link to standard synthesis tools and back-end flows.","PeriodicalId":101717,"journal":{"name":"Proceedings of the IEEE 2001 Custom Integrated Circuits Conference (Cat.
