Temperature-Adaptive Circuits on Reconfigurable Analog Arrays

This paper describes a new reconfigurable analog array (RAA) architecture and an integrated circuit (IC), and its use to map analog circuits that adapt to extreme temperatures. Evolution-driven adaptation takes place on the RAA IC, guided by algorithms implemented in a field programmable gate array (FPGA) collocated with the RAA in the extreme temperature environment. The experiments demonstrate circuit adaptation over a wide temperature range, from extremely low of -180degC to high of 120degC.
