Expanded Device Library

Oct 26 2013, 3:00 PM PDT · 3 comments »

We've added over 100 new device models across MOSFETs, BJTs, diodes, and op-amps to make it easier for you to simulate your designs!

Just double-click on any component within the CircuitLab editor to use one of our standard library models, or create your own models from numerical parameters or from SPICE.

Custom Device Models and SPICE import!

Up until now CircuitLab has had only a limited number of device models in its component library. While you all love our interface and simulations features, our #1 most requested feature has been a more extensive library of components. Today we are releasing the ability for you to save your own device models, and reuse those models later in your other designs.

We have also added the ability to import certain SPICE models for BJTs, MOSFETs, and Diodes directly into CircuitLab, and you can save those models to your personal library for reuse later.

New MOSFET Schematic Symbols

We've always had a single style of schematic symbol for MOSFETs within CircuitLab schematics, but we now have several options available. These three styles are "CMOS" (the original style), "ENH" for Enhancement-mode MOSFETs, and "ENH_BD" which adds a body diode to the symbol.

Here's a sample:

If you get mixed up while building your schematic, just mouse-over any terminal and CircuitLab will tell you if it's the drain or source!
