Field Programmable Analog Circuits and Arrays - An Overview

Integrated analog circuits that can be updated with respect to certain parameters in the field are not new and they are available on the market since many years. However, the production of many commercial solutions that appeared on the market in the last 2-3 decades has been discontinued and also existing literature is often outdated. We here thus want to give a summary of the technology with a focus on commercial devices that are available today, survey recent academic work including some historical aspects, and thereafter compare existing solutions in order to provide an overview on FPAA (Field Programmable Analog Array) technology which is up to date. A number of selected use cases will be presented and analyzed in order to assess possible advantages over e.g. discrete circuits.
