Symbolic approach in design of BaTiO/sub 3/-ceramics capacitive properties [bandpass filters]

This paper presents a method that can establish a correlation between circuit function and manufacturing process parameters of a device. The method is based on the symbolic network function generation and relationship between technological and electrical parameters of an electronic device. The circuit function in the symbolic form enables direct substitution of any electrical parameter with any process parameter needed for the device manufacture. We consider the method in respect of the capacitive property of BaTiO/sub 3/-ceramic. The effects of pressing pressure and sintering temperature on the electrical characteristics of pure barium-titanate were researched. An interpolation function is used for mapping results obtained by measurements on ceramic samples, to the algebraic expression. The approach is illustrated on an example.
