Note: Some older versions of Proteus (before v8.0) may not include a native SPICE model. The user may need to import a third-party SPICE model (e.g., from onsemi.com). Modern versions (8.9 and 9.0+) include a basic behavioral model.
When you place the MC1496 in Proteus, you aren't just placing a black box. The simulation engine models the internal "Gilbert Cell" architecture—a multi-transistor arrangement that allows for precise multiplication of two signals. Proteus Mc1496 Lib
In a Proteus simulation, the MC1496 typically requires three distinct input sources to demonstrate its capabilities: Note: Some older versions of Proteus (before v8
Pro Tip: In Proteus, use the Virtual Oscilloscope to visualize the output. If you wire it correctly, you will see the classic "DSB-SC" (Double Sideband Suppressed Carrier) waveform—where the amplitude envelope changes phase when the modulating signal crosses zero. This is a textbook concept that comes alive visually in Proteus. When you place the MC1496 in Proteus, you

In the Proteus symbol, pins are often numbered 1-10. Verify with the datasheet before simulation.
