Design of a new intelligent CMOS controller chip for control water level in tanks

In this paper, we present a new CMOS chip using fuzzy logic controller architecture to control the level of water in a tank. The flow of water (liquid) will be controlled with controllable valves. A motor controls the valve of the tank. The significant aim of this paper is to reduce both motor and input valve amortization and to increase their useful lifetime with presenting a simple and inexpensive controller for minimizing the movement of the motor valve, at the same time, setting the level of the tank at defined points. The controller is implemented by CMOS chip techniques in 0.35 um CMOS technology. The die size of the chip is 0.042 mm and power consumption is 8mw. The inference speed of the controller is about 4.05 MFLIPS.
