How to do current noise simulation in adel If you are designing analog circuits, you know that current noise is a crucial parameter that affects the performance of your circuit. Current noise is caused by the random motion of charge carriers in a conductor, and it can limit the sensitivity, dynamic range, and signal-to-noise ratio of your circuit. Therefore, it is important to simulate current noise in your circuit to predict its behaviour and optimise its performance.
ADEL (Advanced Design System Electronic Design Automation) is a powerful simulation tool that can help you simulate current noise in your circuit.

What is ADEL?
ADEL is a software package developed by Keysight Technologies that provides a complete solution for electronic design automation. ADEL includes a variety of simulation tools for circuit analysis, optimization, and verification, including frequency-domain and time-domain simulation, optimization algorithms, statistical analysis, and design rule checking.
Also includes a user-friendly interface that allows you to design and analyse your circuits visually, and it supports a wide range of technologies, including RF, microwave, and high-speed digital circuits. ADEL is a popular tool among analog designers because of its accuracy, speed, and ease of use.
How to do Current Noise Simulation in ADEL?
To do current noise simulation in ADEL, you need to follow these steps:
- Create a new project: Open ADEL and create a new project by clicking on “File” > “New Project”. Choose the type of project you want to create (e.g., RF, analog, digital) and specify the name and location of the project.
- Design your circuit: Use the schematic editor in ADEL to design your circuit. Add the components you need, such as resistors, capacitors, and transistors, and connect them according to your circuit diagram.
- Specify the noise sources: To simulate current noise, you need to specify the noise sources in your circuit. You can add noise sources to your circuit by clicking on “Components” > “Noise” and selecting the type of noise source you want to add (e.g., white noise, flicker noise).
- Set up the simulation: Once you have designed your circuit and specified the noise sources, you need to set up the simulation parameters. Click on “Simulate” > “Set up Simulation” and choose the type of simulation you want to perform (e.g., AC analysis, transient analysis).
- Run the simulation: Click on “Simulate” > “Simulate” to run the simulation. ADEL will generate the output data for your circuit, including the current noise spectral density.
- Analyse the results: After the simulation is complete, you can analyse the results using the various tools in ADEL. For example, you can plot the noise spectral density as a function of frequency to see the noise behaviour of your circuit.
