Abstract

A complete digitally-programmable analogue fuzzy logic controller (FLC) is presented. The design of some new functional blocks and the improvement of others aim towards speed optimisation with a reasonable accuracy, as it is needed in several analogue signal processing applications. A nine-rules, two-inputs and one-output prototype was fabricated and successfully tested using a standard CMOS 2.4 μ technology showing good agreement with the expected performances, namely: 5.26 Mflips (mega fuzzy logic inferences per second) at the pin terminal (@CL=13 pF), 933 μW power consumption per rule (@Vdd=5V) and 5 to 6 bits of precision. Since the circuit is intended for a subsystem embedded in an application chip (@CL⩽15 pF) over 8 Mflips may be expected
