ANALOG CIRCUIT FOR WIDE RANGE SENSOR LINEARIZATION OPTIMAL IN UNIFORM NORM

摘要

The present invention relates to a linearization circuit (1) for linearizing of sensors (R T1 , R T2 , R T3 , R TK ) having nonlinear behavior, the circuit comprises; a sensor circuit (2) having a plurality of sub-circuits connected parallel to each other and each of which comprises a sensor (R T1 , R T2 , R T3 , R TK ) and a resistor (R 1 , R 2 , R 3 , R k ), and an inverting operational amplifier (3) having a feedback path (4) where a sensor (R TO ) of the same type in the sub-circuits is connected, and whose inverting input (5) is connected to the sensor circuit (2).
