Nerd Ralph loves cheap and dirty hacks, and for that we applaud him. His latest endeavor is a LiFePO4 battery charger that he made out of parts he had on hand for under $0.50 US. (Although we think he ...

Switches controlled by the input signal amplitude are used as input signal level indicators, input signal level analyzers, power supply voltage indicators, and so on. Such switches are usually made as ...

When we do textbook analysis, we tend to ignore the real-world concerns for the sake of learning. So, a typical theoretical voltage divider is simply two resistors. But if you examine a low-pass RC ...

Determine ID and VGS for the JFET with voltage-divider bias in the figure shown. Given that for this particular JFET, the parameter values are such that VD≅7V. Calculate the gate-to-source voltage as ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
