Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

In 2008, Kendall Castor-Perry began an extended investigation into the effect that bypass capacitor selection has on analog circuit performance. Five years on, we’re re-posting this classic series, ...

Measuring a voltage is pretty easy: just place your multimeter’s probes across the relevant pins and read the value. Probing currents is a bit trickier, since you need to open up the circuit and place ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

Most older and a few current IC op amps have a separate null or trim pin input to which a corrective voltage can be applied. Another solution is to add a resistor in the non-inverting input, which ...

Previous installments of this series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...

The MAX74810, which is fully specified over the extended industrial temperature range of −40 to +125°C, is housed in an ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

ROHM’s ultra-compact complementary metal–oxide–semiconductor (CMOS) operational amplifier (op amp) TLR1901GXZ achieves the ...
