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 change (∆C) from 0% to ...

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 ...

By Aldrick S. Limjoco, Analog Devices Analog Dialogue Introduction Minimizing output ripple and transients from a switching regulator can be important, especially when powering noise-sensitive devices such as high-resolution ADCs, where the output ...

Dennis Hudgins, Texas Instruments As the demand for power efficient systems continues to grow, accurately monitoring system power and energy consumption is increasingly important and is a problem more engineers must solve. One solution to this ...

Shyam Sunder Tiwari Electronic Design Designers seeking a quick and easy frequency source often use a relaxation oscillator (Fig. 1) based on digital gates such as the 74HC14 inverter with hysteresis. The oscillator is also useful in sensor signal ...

6 applications utilizing thermally based circuits are detailed. Included are a 50 MHz RMS to DC converter, and anemometer, a liquid flow meter and others. A general discussion of thermodynamic considerations involved in circuitry is also presented.
