Using current mirror for current sensing in high current MOSFET applications significantly reduces power loss in current sensing circuit and lowers design cost by replacing expensive high power ...

In theory, the design of current sensing circuitry, typically based on simple measurement of the IR voltage developed across a resistor placed in series with the current to be sensed, looks like an ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...

A single-supply, 2.7- ~ 5.5-V, SOT25/SOT26 device from Diodes Inc. features an input common-mode range of up to 26 V. Devices are available to sense unidirectional and bidirectional current. The ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...
