A 19MFLIPS CMOS fuzzy controller to control continuously variable transmission ratio

Implementation of a new fuzzy logic controller in CMOS technology which enhances the control speed and precision of continuously variable transmissions in automobile is presented in this paper. The maximum delay for the proposed fuzzy logic controller is 52 ns that corresponds to 19.23MFLIPS. Mixed analog/digital realization of the circuits makes the controller programmable to various types of companies and automobiles. Simulation results of the controller using HSPICE and level 49 parameters (BSIM3v3) in 0.35 μm standard CMOS technology, demonstrate a power consumption of 6.7 mW, and 2.02% RMS error of output surface compared to ideal results obtained from MATLAB.
