7 MixedSignal
7.16 Id-Vd Mismatch[3]: Id-Vd characteristics mismatch, 3-terminal (A.01.20)
[Supported Analyzer]
B1500A
[Description]
Measures the drain current vs drain voltage characteristics of two MOSFETs, and plots the differences of them.
[Device Under Test]
MOSFET, 3 terminals, 2 ea.
[Device Parameters]
Polarity: Nch (SMUs force the specified value) or Pch (SMUs force the negative specified value).
Lg: Gate length
Wg: Gate width
Temp: Temperature
IdMax: Drain current compliance
[Test Parameters]
IntegTime: Integration time
DrainA: SMU connected to the device A Drain terminal, primary sweep voltage output
DrainB: SMU connected to the device B Drain terminal, synchronous sweep voltage output
Gate: SMU connected to Gate terminal, secondary sweep voltage output
VgStart: Sweep start voltage for Gate terminal
VgStop: Sweep stop voltage for Gate terminal

DrainMinRng: Minimum range for the drain current measurement
[Measurement Parameters]
Device A Drain current IdrainA
Device B Drain current IdrainB
[User Function]
Drain conductance gds_A=diff(IdrainA,VdrainA)
Drain conductance gds_B=diff(IdrainB,VdrainB)
Drain resistance Rds_A=1/gds_A
