This paper presents a fully configurable framework for analog integrated circuit design automation. The goal of this framework, named as UCAF, is to provide in a single environment several optimization heuristics, design methodologies and technology options in order to allow for the designer the possibility to perform a set of comparisons and selections(More)
This paper presents the design and characterization of fully differential amplifiers for application in an automatic circuit sizing tool. The tool uses Simulated Annealing as main optimization heuristic and electrical simulations for circuit specifications evaluations. The methodology is based on the minimization of a cost function and a set of constraints(More)
The goal of this paper is to analyze the gm/I D methodology for automatic sizing of analog integrated amplifiers. This methodology exploits the analytical gm/ID methodology, in which the inversion level of the transistors are free variables and gate width and length are defined in terms of the technology independent gm/ID versus ID/(W/L) curve. Genetic(More)
The goal of this paper is to present a tool for automatic synthesis of analog basic integrated blocks using the genetic algorithm heuristic and external electrical simulator. The methodology is based on the minimization of a cost function and a set of constraints in order to size circuit individual transistors. The synthesis methodology was implemented in(More)
This paper proposes a methodology for automatic synthesis of analog basic building blocks. The methodology is based on the minimization of a cost function composed by the variables of an analog block (transistor lengths and widths). The implementation was made in Matlab, with a generic non-linear optimization function and an external electrical simulator(More)
