Abstract

Cooperative analog-digital signal processing (CADSP) is directed at allowing freedom of movement of the partition between the analog and digital systems. By allowing more of the computation to be performed in low{ power analog circuits, cooperative analog-digital signal processing enables advanced signal processing functionality for very low-power systems and smart sensors. However, development and characterization of advanced analog VLSI systems is a lengthy process requiring a high level of expertise. This makes it difficult and time-consuming to perform research and develop applications of the technology. Research Program: The research plan entails the development of a very high-density field-programmable analog array (FPAA) based on floating-gate analog circuits. This FPAA device will be used in conjunction with a traditional digital field-programmable gate array (FPGA) for rapid development and testing of CADSP systems.
