i think this question is very important.
We must know Vds to make MOSFETs in saturation region.
if not, there would always be possibilities that a transistor falls in a linear region as Vds is lower than Vdsat.

Of course, i can calculate Vds in a CS AMP with a drain resistor.
I mean, in the other configurations, we should also know Vds.

How can i calculate it?

Well you need to use your circuit theory knowledge and solve for Vds.
Also you can show as a circuit that you have a problem with.

1. How can I calculate Vds before simulation?

Vds, or drain-to-source voltage, can be calculated by using the equation Vds = Vd - Vs, where Vd is the drain voltage and Vs is the source voltage. These values can be determined through circuit analysis or by using a multimeter.

2. Can I estimate Vds using the datasheet of the component?

Yes, the datasheet of a component can provide valuable information about its voltage characteristics, including Vds. However, it is important to note that the actual Vds may differ slightly from the estimated value due to circuit conditions and other factors.

3. How does the value of Vds affect the performance of a circuit?

The value of Vds plays a critical role in determining the operating point of a circuit. It affects the output characteristics, power dissipation, and efficiency of the circuit. It is important to select a suitable Vds value to ensure optimal circuit performance.

4. Can I use simulation software to determine Vds?

Yes, simulation software can be used to predict the value of Vds before actually building the circuit. The software uses mathematical models and circuit analysis techniques to simulate the behavior of the circuit, including the Vds value.

5. How can I ensure the accuracy of the Vds value obtained from simulation?

To ensure the accuracy of the Vds value obtained from simulation, it is important to use reliable simulation software and input accurate parameters and circuit configurations. Additionally, performing multiple simulations with varying conditions can help validate the results.
