It allows a designer with network access to interactively explore a circuit design space of pre-characterized circuit topologies using a convenient graphical user interface. Any user can extend the system to include new or custom circuit topologies without a lot of programming effort by writing their own design specification files. Designers will benefit from the use of the application as it will enable them to obtain a deeper understanding of the operation of their circuits and the performance tradeoffs that are possible for pre-characterized circuit topologies. The enhanced understanding gained by the designers will result in better design realizations and will accelerate the development of improved topologies in the future. Several benefits accrue due to the use of the network-centric computing paradigm of which the most significant is the enhanced communication of design knowledge and prevention of reinvention by the use of a centralized design knowledge repository.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.

A two-step approach is adopted to speed up the estimation process and handle larger analog systems. In the first step, the performance of basic analog components is estimated using a knowledge-based approach. Then, component models are generated with the estimates produced at this phase. In the second phase, we use a symbolic analysis methodology to evaluate the performance at the system level. The system net-list is represented by a signal flow graph (SFG) using the component models generated at the previous phase. The SFG approach allows one to handle feedback loops at the system level.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.

The environment is based on a high level optimizer and a circuit level optimizer. The non-idealities of the SC building blocks are considered at high level and incorporated as macromodels. This enables the accurate estimation of filter parameters which are passed to the circuit level optimizer for transistor level synthesis. The optimization strategy at circuit level combines evolution strategies with simulated annealing in finding the global optimum solution. The algorithmic details of the synthesis system are discussed and illustrated examples that demonstrate the validity of the approach are presented.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.

The basis involves a new signal space consisting of real-valued signals and discrete moment signals expressed by real time functions and delta function series, respectively, a notation of uniform rate sampling in the space, a method to distinguish among system classes, novel names of conceivable sorts of dynamical linear or discretely linear systems and a unified representation of these systems. To demonstrate the availability of the basis, a system model, with sampling, of a 0-th order hold element is shown and extended to those of approximate circuits of ideal low-pass filters. Finally, conventional sampled-data system models of interpolating circuits are denied because of false counter-examples of Shannon's sampling theorem.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.
