Linear transfer function synthesis using non-linear IC components

This paper describes a methodology for the synthesis of linear transfer functions based on the use of non-linear components. Rather than using local linearisation techniques to eliminate the unwanted non-linearity, the non-linear characteristic of the component is directly incorporated into the state-space description of the network transfer function. Although this approach has been recently applied as the log-domain technique, in this paper the approach is generalised to include both CMOS and bipolar technologies.
