In this paper, the authors present a constant voltage constant current readout circuit for Ion-Sensitive Field-Effect Transistor (ISFET). The study and investigation of ISFET performance using linear ...

Some circuits require a constant-current source thatdoesn’t necessarily connect to a power-supply rail or toground. The circuit in Figure 1 shows a simple method forachieving that configuration.

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

A current-limiting circuit is often needed to protect the most expensive parts of the circuit from transients such as current spikes, which occur when a power supply is driving a large capacitive load ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has expanded its lineup of stepping motor driver ICs with the launch of “TB67S549FTG,” a stepping motor ...

Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...
