A schematic diagram is not a detailed blueprint of an analog circuit; instead, it’s more like architectural sketch of the circuit. Look at any schematic for a CMOS analog IC circuit and you will see ...

QSPICE is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and reliability. It is a new program and can be downloaded here. QSPICE is still in the demonstration ...

The basis of almost everything we discuss here on ExtremeTech is the transistor -- but just above that is a topic that we usually skirt around because no one, even hardcore nerds, really know anything ...

How to use statistical tools for component tolerance analysis. A look at methods such as Monte Carlo and Gaussian distribution. Simulating a dc-dc converter in LTspice to model closed-loop voltage ...

In the desktop 3D printing world, we’re fortunate to have multiple online repositories of models that anyone can load up on their machine. Looking to create a similar experience but for electronic ...

We’d wager that, if you’re reading Hackaday, you’ve looked at more than a few circuit diagrams in your day. Maybe you’ve even converted a few of them over to a PCB. It’s a workflow that, at this point ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
