The MC1496 is a balanced modulator/demodulator integrated circuit (IC) used for signal processing tasks like amplitude modulation (AM), synchronous detection, and FM detection. In Proteus, you can typically find this component or add it through the following methods: Finding the MC1496 in Proteus
Internal Library: Most standard versions of Proteus already include the MC1496. You can find it by: Opening the Schematic Capture window.
Pressing the 'P' key on your keyboard to open the "Pick Devices" window. Searching for "MC1496" in the keywords box.
Web Search and Import: If the component is missing from your local library, professional users can use the built-in Web Search and Import tool to download the schematic part, PCB footprint, and 3D model directly. Downloading External Libraries
If you need to download a custom library file (e.g., proteusmc1496lib.lib), you can use third-party repositories: Proteus Mc1496 Lib
SnapMagic (formerly SnapEDA): Provides free symbols, footprints, and 3D models for the MC1496 by Onsemi.
Ultra Librarian: Another popular site for finding verified Proteus component libraries. How to Import a Library File
If you download a library file (often in .pdif or .lib format), follow these steps to add it to Proteus: Open Schematic Capture. Navigate to Library > Import Parts in the top menu. Click Select File and browse for your downloaded file. Select the part and click Import Part to finalize. MC1496 Symbol, Footprint & 3D Model by Onsemi - SnapMagic
The MC1496 is a versatile high-frequency communication IC (operable up to 300 MHz) used for: Set the transient analysis for 5 ms (enough
Amplitude Modulation (AM) and Double-Sideband Suppressed Carrier (DSB-SC) generation.
Demodulation (Synchronous detection, FM, and phase detection). Mixing and frequency doubling.
Internal Architecture: It utilizes a Gilbert cell structure with differential amplifier pairs (Q1–Q4 driven by Q5–Q6). Adding the MC1496 Library to Proteus
To use the MC1496 in your designs, follow these steps to install a downloaded library (often found on platforms like SnapMagic or The Engineering Projects): Category: Modulators or Category: Analog ICs
Expected Result: If the library model is correct, you should see a DSBSC waveform – a 100 kHz carrier whose amplitude varies sinusoidally at 1 kHz, with a phase inversion at the zero crossing of the modulating signal. If you see a standard AM waveform (carrier always present), your biasing or input levels are off – a good test of the model’s accuracy.
Adjust the amplitude of the modulation input. You should see the classic Double Sideband Suppressed Carrier (DSBSC) waveform. Why this matters: A generic multiplier won't show the slight carrier leak visible at zero-crossing. A proper MC1496 library will simulate real leakage.
If your installation lacks the model, follow these steps to source it:
Unlike modern microcontrollers (like an STM32 or Arduino) which have specific, branded libraries in the Proteus Center, the MC1496 is a "primitive" analog component.
New users often search for a downloadable library file (.LIB or .HEX) only to find that the MC1496 is usually built directly into the standard simulation models of Proteus. It typically resides under the category:
If it is missing from your installation (common in very old versions like 7.x), you aren't looking for a "library" in the software sense—you are looking for a SPICE Model. Proteus relies on the SPICE (Simulation Program with Integrated Circuit Emphasis) engine to mathematically calculate the behavior of analog circuits. To get the MC1496 working, you often need to import a .mod or .sub file containing the mathematical definitions of the chip’s internal transistors.
