How to

How to use a circuit diagram template.

  1. 01Choose your gate type

    Select NAND, NOR, XOR, or XNOR from the library to start with a standard CMOS topology.

  2. 02Configure inputs

    Set the number of inputs (e.g., 3-input) and define the logic function you need.

  3. 03Customize the schematic

    Adjust transistor sizes (W/L ratios), add labels, and tweak the layout for your design requirements.

  4. 04Verify the pull-up/pull-down network

    Review the CMOS structure to ensure correct logic operation and performance.

  5. 05Generate and export

    Click generate to render your circuit diagram, then download as PNG or SVG for documentation or sharing.

FAQ

Questions about circuit diagram templates

What is a CMOS logic gate?

A CMOS logic gate uses complementary pairs of p-type and n-type MOSFETs to implement logic functions with low power consumption.

How do I create a 3-input CMOS NAND gate?

Place three PMOS transistors in parallel and three NMOS transistors in series; connect as shown in the example. The output is low only when all inputs are high.

Can I customize transistor sizing?

Yes, our diagram generator allows you to specify W/L ratios for each transistor to meet performance targets like speed or drive strength.

Are these diagrams suitable for academic papers?

Absolutely. You can export high-resolution SVG or PNG for inclusion in reports, theses, or presentations.

What other gate types are supported?

Besides NAND, NOR, XOR, XNOR, you can build AND, OR, NOT, and complex gates by combining basic cells in the editor.
