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 (RT1, RT2, RT3, RTK) 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 (RT1, RT2, RT3, RTK) and a resistor (R1, R2, R3, Rk), and an inverting operational amplifier (3) having a feedback path (4) where a sensor (RTO) of the same type in the sub-circuits is connected, and whose inverting input (5) is connected to the sensor circuit (2).
