Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

The simple circuit design in Figure 1 lets you measure all components of a current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...

Figure 1 gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components. In this design, the output is connected to the input of the gadget when you press the push ...

In a signal-conditioning op-amp application there are a number of different approaches to take—what noise and SFDR advantages might one offer over another. In designing an input stage for an analog-to ...

Accountants and MBAs use spreadsheets to play “what if” scenarios with business and financial data. Can you do the same thing with electronic circuits? The answer–perhaps not surprisingly–is yes.
