Adaptive Power Optimization is Revolutionizing PMICs
“There is no better way to save energy and cut bills than by turning all electronic devices off.”
This basic piece of advice is the underlying principle and philosophy behind any form of energy management applied to energy consumption optimization, and in general in so-called adaptive power optimization.
In the case of battery powered …
Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required.
Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and discharged in shorter time than batteries, yet with …
One of the best ways to ensure a MOSFET is functioning properly and meets specifications is to determine its characteristics by tracing I-V curves. There are a number of output characteristics requiring I-V tests; you can derive gate leakage, breakdown voltage, threshold voltage, transfer characteristics, and drain current all by simply tracing I-V characteristics and verifying the device is …

Basic Parameters for Choosing an Oscilloscope
Oscilloscope Bandwidth
Bandwidth is a key spec that determines the highest frequency your oscilloscope can measure accurately. It's a vital consideration affecting both the functionality and cost of the oscilloscope.
The higher the bandwidth, the more accurate the reproduction of your signal, as illustrated with a signal captured at 250 MHz, 1 GHz …
An oscilloscope, formerly known as an oscillograph (informally scope, oscope, or o-scope), is an instrument that graphically displays electrical signals and shows how those signals change over time. It measures these signals by connecting with a sensor, which is a device that creates an electrical signal in response to physical stimuli like sound, light and heat. For instance, a microphone is a …
An oscilloscope probe is a device that makes a physical and electrical
connection between a test point or signal source and an oscilloscope.
Depending on your measurement needs, this connection can be made with something as simple as a length of wire or with
something as sophisticated as an active differential probe. Essentially, a probe is some sort of device or network
that connects the signal …
A signal generator is an analog or digital device that engineers use to create electronic signals when testing circuit designs. There are many different types of signal generators with diverse features and applications. Below are the most common types of signal generators and the unique capabilities of each.
Waveform or function generators
Waveform generators produce electrical waveforms over a …
Failing EMI compliance testing can be a design engineer’s worst nightmare. Additional compliance testing costs, external lab testing, debug engineering time, and in some cases, board spins can add significant costs and time delays to your project. Unfortunately, for companies new to EMI/EMC, estimating compliance testing cost can be somewhat challenging. In this blog, we’ll provide information on …
Though it’s not uncommon to measure current with a digital multimeter, measuring current that changes over time requires the use of an oscilloscope. Most oscilloscopes only directly measure voltage, not current, however you can measure current with an oscilloscope, using one of two methods.
Measure the voltage dropped across a shunt resistor: Some power supply designs may have shunt resistors …
