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 ...

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 ...

Process devices operate when an input level, such as voltage, reaches the required value for the device to operate. The transistor is on, when the input voltage is greater than or equal to \(0.7 V\).

Last time I showed you how to set up a reasonably complex design in a spreadsheet: a common emitter bipolar transistor amplifier. Having the design in a spreadsheet makes it easy to do “what if” ...

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 ...
