Thermistor Evaluation Using the Agilent B2900A Series of SMUs Technical Overview Agilent B2901/02/11/12A Precision Source/Measure Unit Agilent B2901A Precision SMU, 1ch, 100 fA resolution, 210 V, 3 A DC/10.5 A pulse Agilent B2902A Precision SMU, 2ch, 100 fA resolution, 210 V, 3 A DC/10.5 A pulse Agilent B2911A Precision SMU, 1ch, 10 fA resolution, 210 V, 3 A DC/10.5 A pulse Introduction Agilent B2912A Precision SMU. 2ch, 10 fA resolution, 210 V, 3 A DC/10.5 A pulse The thermistor is a resistor with resistivity that varies as a function of temperature. Typical thermistor applications are thermal sensing and electric circuitry protection. However, the thermistor's sensitivity to temperature changes can work against measurement accuracy since Joule self-heating during measure- ment can alter device characteristics. This means that accurate thermistor characterization requires both precise low-current resistance measurement capability and pulsed bias measure- ment capability (to minimize tempera- ture change during measurement). The Agilent B2901/02/11/12A Precision Source/Measure Unit is a compact and cost-effective bench- top Source/Measure Unit (SMU) with the capability to output and measure both voltage and current. The B2900A Series of SMUs also supports a resistance measurement function that facilitates both low and Figure 1. Using the B2900A Series of SMUs to characterize a thermistor high resistance measurements. The B2900A Series of SMUs enables you to make a wide range of resistance that make it easy for you to begin Figure 1 illustrates the connections measurements more accurately and making productive measurements necessary for measuring a thermistor quickly than ever before. immediately. using a member of the B2900A Series of SMUs.
