Linearizing circuit for thermistor
NettetSuppose you've been asked to design a linearized thermistor circuit, with a temperature range centered around +25 deg C. One technique is easy - place a resistor in parallel with the NTC thermistor. But first, to get a feel for the R vs. T curve, check out the table below. T (deg C) R (Ohms) -15. 63338. Nettetproposes a design with temperature range selection circuit, so that the thermistor linearizing circuit automatically switches to a corresponding linearity calibration loop and the method is implemented in TSMC 0.5μm CMOS high voltage mixed signal based polycide. A total of four states are described circuit.
