Examples of Calculating Accuracy
Example 1: Calculating 5 °C Accuracy
Calculate the accuracy of 900 nA output in the 1 µA range under the following conditions:
ambient temperature | 28 °C |
internal device temperature | within Tcal ± 5 °C |
self-calibration | within the last 24 hours. |
Solution
Since the device internal temperature is within Tcal ± 5 °C and the ambient temperature is within 23 °C ± 5 °C, the appropriate accuracy specification is:
0.03% + 100 pA
Calculate the accuracy using the following equation:
Therefore, the actual output will be within 370 pA of 900 nA.
Example 2: Calculating 1 °C Accuracy
Calculate the accuracy of 900 nA output in the 1 µA range. Assume the same conditions as in Example 1, with the following differences:
internal device temperature | within Tcal ± 1 °C |
Solution
Since the device internal temperature is within Tcal ± 1 °C and the ambient temperature is within 23 °C ± 5 °C, the appropriate accuracy specification is:
0.022% + 40 pA
Calculate the accuracy using the following equation:
Therefore, the actual output will be within 238 pA of 900 nA.
Example 3: Calculating Remote Sense Accuracy
Calculate the remote sense accuracy of 500 mV output in the 600 mV range. Assume the same conditions as in Example 2, with the following differences:
HI path lead drop | 3 V |
HI sense lead resistance | 2 Ω |
LO path lead drop | 2.5 V |
LO sense lead resistance | 1.5 Ω |
Solution
Since the device internal temperature is within Tcal ± 1 °C and the ambient temperature is within 23 °C ± 5 °C, the appropriate accuracy specification is:
0.016% + 30 μV
Since the device is using remote sense, use the remote sense accuracy specification:
Add (3 ppm of voltage range + 11 µV) per volt of HI lead drop plus 1 µV per volt of lead drop per Ω of corresponding sense lead resistance to voltage accuracy specifications.
Calculate the remote sense accuracy using the following equation:
Therefore, the actual output will be within 158.2 µV of 500 mV.
Example 4: Calculating Accuracy with Temperature Coefficient
Calculate the accuracy of 900 nA output in the 1 µA range. Assume the same conditions as in Example 2, with the following differences:
ambient temperature | 15 °C |
Solution
Since the device internal temperature is within Tcal ± 1 °C, the appropriate accuracy specification is:
0.022% + 40 pA
Since the ambient temperature falls outside of 23 °C ± 5 °C, use the following temperature coefficient per degree Celsius outside the 23 °C ± 5 °C range:
0.0006% + 4 pA
Calculate the accuracy using the following equation:
Therefore, the actual output will be within 266.2 pA of 900 nA.
Examples of Determining Extended Range Pulse
Parameters and Optimizing Slew Rate using NI SourceAdapt
Example 1: Determining Extended
Range Pulse On Time and Duty Cycle Parameters for the PXIe-4139 (40W)
Determine the extended range pulsing parameters, assuming the following operating point.
Output function | Pulse Current |
Pulse voltage limit, Vpulse | 40 V |
Pulse current level, Ipulse | 6 A |
Bias voltage limit, Vbias | 0.1 V |
Bias current level, Ibias | 0 A |
Pulse on time, ton | 1.5 ms |
Chassis' slot cooling capacity | ≥58 W |
Solution
Begin by calculating the pulse power using the following equation.
For PXIe-4139 (40W), refer to the following figures to identify next steps. First, verify the the region of operation using Definition of Pulsing Terminology, which shows 240 W is in the extended range pulsing region.
Next, refer to Pulse On-time vs Pulse Current and Pulse Voltage, which shows the maximum pulse on time, ton, is limited by the maximum pulse energy, EpulseMax. Use the pulse energy equation (Equation 2) from Extended Range Pulsing for PXIe-4139 (40W) to calculate the maximum pulse on time, tonMax(Equation 6).
Next, refer to Duty Cycle vs Pulse Current and Pulse Voltage, which shows the maximum duty cycle, D, is limited by the cycle average power, PCA.If the required pulse on time is 1.5 ms and the module is installed in a chassis with slot cooling capacity ≥58 W, use the cycle average power equation (Equation 5) from Extended Range Pulsing for PXIe-4139 (40W) to calculate the minimum pulse off time, toffMin(Equation 7).
Finally, verify that the pulse cycle time, tcycle, is greater than or equal to the minimum pulse cycle time, tcycleMin (5 ms). To calculate the pulse cycle time, use the following equation:
In this case, the pulse cycle time meets the minimum pulse cycle time specification.
Therefore, a 40 V, 6 A pulse with an on time of 1.5 ms and a pulse off time of 7.5 ms is supported, since it fulfills the following criteria:
- Greater than the minimum pulse on time of 10 μs
- Equal to the minimum pulse off time of 7.5 ms to meet maximum cycle average power
- Greater than the minimum pulse cycle time of 5 ms
Example 2: Determining Extended Range Pulse
On Time and Duty Cycle Parameters for the PXIe-4139 (20W)
Determine the extended range pulsing parameters, assuming the following operating point.
Output function | Pulse Current |
Pulse voltage limit, Vpulse | 40 V |
Pulse current level, Ipulse | 6 A |
Bias voltage limit, Vbias | 0.1 V |
Bias current level, Ibias | 0 A |
Pulse on time, ton | 1.5 ms |
Chassis' slot cooling capacity | ≥58 W |
Solution
Begin by calculating the pulse power using the following equation.
Since the pulse power of 240 W is within the 500 W region of Figure 2, the maximum configurable on time is 400 μs and maximum duty cycle is 2%.
For example, if the required pulse on time is 100 μs, and the required pulse cycle time is 10 ms, calculate the pulse off time and verify the duty cycle using the following equations.
Therefore, a pulse with an on time of 100 μs and 1% duty cycle would be supported, since it fulfills the following criteria:
- Greater than the minimum pulse on time of 50 μs
- Less than the maximum pulse on time of 400 μs and duty cycle of 2%
- Greater than the minimum pulse cycle time of 5 ms
Example 3: Using NI SourceAdapt to
Increase the Slew Rate of the Pulse
Determine the appropriate operating parameters and custom transient response settings, assuming the following example parameters.
Output function | Pulse Current |
Pulse voltage limit, Vpulse | 50 V |
Pulse current level, Ipulse | 5 A |
Bias voltage limit, Vbias | 0.1 V |
Bias current level, Ibias | 0 A |
Transient response | Fast |
Load, cable impedance | 4.5 Ω, 40 μH |
Pulse on time, ton | 10 μs |
Pulse off time, toff | 4.99 ms |
The SMU Transient Response can be configured to three predefined settings, Slow, Normal, and Fast. If these settings do not provide the desired pulse response, a fourth setting, Custom, enables NI SourceAdapt[18]18 Visit ni.com for more information about NI SourceAdapt Next-Generation SMU Technology. technology which provides the ability to customize the SMU response to any load, and achieve an ideal response with minimum rise times and no overshoots or oscillations.
Solution
SourceAdapt allows users to set the desired gain bandwidth, compensation frequency, and pole-zero ratio through custom transient response to obtain the desired pulse waveform. To use SourceAdapt, first set the Transient Response to Custom.
To achieve the resulting waveform in the following figure, use the parameters in the following table.
Transient response | Custom |
Current: Gain bandwidth | 260 kHz |
Current: Compensation frequency | 140 kHz |
Current: Pole-zero ratio | 0.75 |
Gain bandwidth is directly proportional to the step response slew rate. The higher the gain bandwidth, the higher the slew rate. It is worth noting that increasing the gain bandwidth will likely increase ringing. However, this can likely be removed by appropriately setting the compensation frequency and the pole-zero ratio.
Compensation frequency and pole-zero ratio are used to determine the frequencies of the SMU control loop pole and zero, which can be used to optimize the system transient response by increasing phase margin and reducing ringing. To reduce the overshoot, it is recommended to set the compensation frequency close to the overshoot ringing frequency, see Fc in Figure 3, and set the pole-zero ratio to be greater than 1.
For reference, the pole frequency and zero frequency are derived by the following equations.
These settings can be accessed through the Transient Response set to Custom: Voltage or Current.
