At the heart of a transceiver is usually a phase-locked-loop (PLL) synthesizer, which delivers a signal to downstream components such as mixers, filters and power amplifiers. At higher frequencies, ...

Simplicity and low cost sustain the popularity of passive PWM DAC ripple filters despite their limitations. One of these limitations is a high output impedance caused by the series sum of filter ...

Why the power-delivery network is critical in modern power electronics. How integrated voltage regulators can improve the PDN and simplify the PCB design. How IVRs improve power delivery to processors ...

Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...

Numerous test-and-measurement applications require a high-frequency magnetic field. Oftentimes, high field strength is needed. Examples of such applications include bio-medicine research on the effect ...

What are the risks when driving a 4 or 6 ohm speaker with a amplifier that is rated from 8-16ohm. The amplifier is an old Pioneer VSX-808, it´s my "PC speakers" and I´m using 4 ohm speakers as front ...

When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...
