If You Have a Problem
When You Make a Measurement
If Measured Value Oscillates when Measuring Negative
Resistance
If the DUT has negative resistance characteristics, SMU may oscillate. Because
SMU operates as negative feedback amplifier.
To solve this problem:
• For voltage controlled negative resistance device
• Connect G in parallel with your DUT to cancel negative resistance. To
obtain an output I-V curve, use the following equation.
IY = I - G × V
• For current controlled negative resistance device
• Connect R in series with your DUT to cancel negative resistance. To obtain
an output I-V curve, use the following equation.
VZ = V - R × I
• If the resistance of the DUT is less than 1 MΩ, you can use a series resistor
built into the SMU.
