Opamp Models
High-fidelity SPICE opamp models supporting all simulator syntaxes.
Precision modeling for analog and mixed-signal circuit design.
AEi Systems has a new streamlined and accurate process for creating high fidelity SPICE Opamp models. These models are a cut above many models (Boyle, Model Editor) found on the web and in EDA software packages.
If you are interested, we support all simulator syntaxes (PSpice, LTspice, QSPICE, Keysight ADS, etc.) Please let us know if we can support you in any way or quote a model for you.
Sample Opamp Models and Reports
- NCS2006 SPICE Model NCS2006 SPICE Model - SPICE Model Sample
- NCS2006 Report NCS2006 Report - Validation Report
How Do We Get the Data
- Usually vendor supplied - though we confirm the data sets
- In-house Testing - AEi Systems has its own lab with state-of-the-art test equipment
Customized Test Boards
AEi Systems generally produces its own test boards since vendor supplied Evaluation Boards are generally inadequate for testing the high frequency aspects of opamp performance.
Support for Other SPICE and Analog Simulation Syntaxes
AEi Systems can provide translations of these models to other simulators. Please contact AEi Systems for pricing and options. We support all SPICE syntaxes, ADS, Simplis, and others.
Effects AEi Systems Opamp Models Emulate
- AC Gain/Phase - Multiple Poles/Zeros from proprietary information
- Input Common Mode Impedance
- Input Differential Mode Impedance
- Offsets and Biases versus Temperature
- Offset Voltage Drift with temperature
- AC Common Mode Rejection Ratio (CMRR)
- DC Common Mode Input Range
- AC Power Supply Rejection Ratio (PSRR) versus Frequency
- Closed Loop Output Impedance versus Frequency
- Output Short Circuit Current versus Power Supply Voltage
- Output Voltage Saturation versus Output Current
- Slew Rate versus Temperature
- Small/Large Signal Pulse Response
- Quiescent Current versus Power Supply Voltage
- Input Noise Voltage Density versus Frequency
(All tests are at a specific supply voltage, temperature, and load current, unless otherwise noted)
Worst Case Models
AEi Systems can work with you to add worst case tolerances including temperature, aging, and radiation effects (BOL or EOL tolerances), in order for you to perform worst case circuit analysis.
