Richtek Technology With huge choice of LED lamps available nowadays, it is not always easy to select the best suitable lamp for your living room or workspace. The light quality of LED lamps can vary greatly depending on the lamp design topology and ...

For a wide variety of products, manufacturing processes require highly precise and reliable temperature measurement technologies. Temperature is often measured through direct contact with a sensor, for example, through immersion of a sensor in ...

Where there is power there is heat, and where there is heat there is often a need to sense temperature (the most widely sensed physical variable). What we call temperature is our measurement of a material’s thermal energy, and there are many ...

Analog Dialogue Question: How could I measure the light intensity of different light sources? Answer: Take a red, green, blue LED. Determination of the light intensity can be crucial, for example, if you want to design the lighting of a room, or in ...

Michael Gambuzza EDN An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the value of the capacitance ...

Johnnie Hancock, Keysight Technologies Electronic Design A digital phosphor oscilloscope is also a digital storage oscilloscope, and the same can be true in reverse. So what exactly separates the two? DSO stands for digital storage oscilloscope. ...

Often used for overcurrent protection, current-sense amplifiers are now finding homes in a wide array of applications, including automotive electronic fuses and three-phase motor control. If you're seeking a way to measure current and power in ...

Alfredo Medina Mohamed Ismail EDN Power accumulators enable a variety of applications that require average power measurement. One example is real-time measurement of switching converter efficiency, which permits converter efficiency evaluation over ...

Alfredo Medina Mohamed Ismail EDN Part 1 PMIC Power Consumption To prolong battery life, it becomes crucial to monitor PMIC voltage rails and determine system performance based on power consumption. Power accumulation diagnostics can be used to ...

Vardan Antonyan EDN Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts. Fortunately, you can convert a ...
