I learned some basic electronics in high school physics class: resistors, capacitors, Kirchhoff’s law and such, and added only what was required for projects as I did them. Then around 15 years ago I ...

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 ...

What are the challenges for real-time biosensing and “edge” analysis? How do gold and gold-silver nanowires address the issue? How these sensors can implement elementary logic functions. Wearable ...

This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are ...

Designing, constructing, testing, and improving circuits—especially those with significant analog content—was always one of my interests. The fact that you could arrange standard active and passive ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...
