A fuzzy logic function generator (FLUG) based on the singleton fuzzy control algorithm is proposed. The normalizing operation can be removed from the original algorithm by introducing a new t-norm operation. The FLUG can be simply implemented with the current mode CMOS circuits, because the dividers are not needed. Further, to solve the problem in the current mode with respect to the restriction of the fan-out number, voltage-input, and current-output membership function circuits are constituted of operational transconductance amplifiers (OTAs), and they are used in the input parts of the FLUG. Due to the simple circuitry, the FLUG can be applied to a basic cell for the analog application-specific ICs
