Abstract

A field programmable analog array (FPAA) appropriate for industrial control is presented and analyzed. The system consists of configurable analog blocks (CABs) with G/sub m/-C circuits and programmable interconnection networks so that FPAA can be reconfigured to implement many analog filters. A method of negative feedback has been used to improve the linearity of transconductance of the amplifiers In this work. The entire FPAA is designed under the environment of a TSMC 0.35 /spl mu/m process.
