Finally, the User Database is where custom components are saved that can be used only by the specific designer. The Corporate Database is where you can save custom components to be shared with colleagues. The Master Database contains all shipping components in a read-only format. The Component Browser organizes the database components into three logical levels. The Select a Component window appears (also known as the Component Browser), as shown in Figure 2.

Therefore, if R1 = R2, then the gain is equal to 2, which you will verify when you run interactive simulation in Multisim.įigure 1. Non-inverting amplifier circuit.īegin by drawing your schematic in the Multisim environment. The gain of this non-inverting amplifier is calculated by the expression Gain = 1 + R1/R2. Sampling time of first reading is different than the sampling time of second reading as meter is used to take one sample and then taking second reading ( after noting it down).įor this test, voltmeters with sample and hold function simultaneously triggered would give better results.For this introductory example, you will simulate a standard non-inverting operational amplifier circuit (shown in Figure 1). Sampling time is different and hence another reason for error.

This condition is different than in schematic in simulator. Meter internal resistance was put in parallel to only one capacitor at a time. That is voltage was first checked on one capacter, and then on the other.

Only one multimeter was used practically. It reaches the values of the matlab results after few minutes of simulation on my computer. I have posted screen capture at the start of simulation earlier. I simulated and found that the result on start on MULTISIM is exactly the same as mathematical calculations done. The charge on capacitors are rising initially with time. The results of Computer Simulation is on Matlab but are taken after what time when simulation started? It is not steady state.

In post #6, i think it does not prove anything except that the mathematical calculatins are correct.
