A field programmable analog array and its application

Abstract

A Field Programmable Analog Array (FPAA) is presented based on switched capacitor technology. The architecture offers an unconstrained topology similar to its digital counterpart, containing an array of identical undedicated analog cells. This makes it possible to program both the functionality of each cell and the interconnect between cells. As a result a large number of diverse architectures may be implemented. The analog array can be programmed to perform many of the routine tasks associated with control systems design. Its linear and non-linear signal processing abilities can provide a wide range of waveform generation functions. The device can also be programmed for precise phase and magnitude characteristics. Some examples related to control systems are discussed.
