Abstract
This paper presents an application of evolutionary programming to parameter optimization in the design of a voltage reference circuit Designing circui ts consists of two steps: topological design and parameter determination. A fter designing a topology suitable for the circuit, the designer selects an appropriate value for each circuit element from a circuit analysis and his experience. This step is difficult and time consuming because the designer must consider many factors simultaneously. As more precise circuits are re quired, parameter optimization becomes more complex. The voltage reference circuit, which requires a precise reference voltage independent of power fl uctuation and temperature change, is such an example. In this paper, evolut ionary programming is used as an effective method of finding good parameter values for the elements of the voltage reference circuit. Simulation resul ts show that this method provides good performance and can be used as an ef fective method for circuit design.
