A Field Programmable Analog Fuzzy Processor with Enhanced Temperature Performance

A field programmable analog fuzzy processor that supports 15 rules, three inputs and one output has been fabricated and tested. The chip area using a CMOS 0.7¿m n-well technology is 32mm2 with the analog core less than 7% of the total. Power consumption at 5V power supply is less than 45mW. The circuit functionality has been tested for power supply ranging from 4.75V to 5.2V and temperature in the interval between 0°C and 70°C. Applying a step input function, the output reaches a stable value in less than 0.6¿sec.
