Native SPICE elements that accurately replicate an op amp’s real-world behavior were nonexistent. A transconductance sourcing current from the rails and transitioning to a resistive state as the ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Analog fault simulation in mixed‐signal circuits is a critical tool for ensuring the robustness and reliability of systems that integrate both analogue and digital components. This field addresses the ...

QSPICE circuit simulation software raises design productivity in power and analogue designs through simulation, said Qorvo. It is designed for analogue simulation and allows designers to simulate ...

I recall excitedly listening to one of my early tech mentors explain the concept of analog computing: “You can easily use op amps to sum and scale any signals, do calculus, or any math you can think ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...
