Commercial Computer-Aided Design Software Optimises DRO Circuit Design

Since DRO design can be both time consuming and costly, CAD techniques may appear to be an obvious solution. In this paper we investigate to see whether the oscillator performance is compromised. The (design is done on a personal computer using the EEsof Touchstone package. Touchstone allows the analysis to be performed in terms of the physical models and structures. It supports two powerful routines for optimisation and tuning. The optimisation facility will, automatically adjust circuit parameter to meet specified circuit characteristics. The tuning facility allows the user to interactively alter or tune individual circuit components to achieve a partxular response.
