Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

Analog Circuit Analysis can be difficult. Consider the circuit below. It includes a Series Resonant Circuit. With Ideal Impedances, the Series Impedance is equal to zero at the resonant frequency. A ...

CMOS mixers are integral components in modern radio frequency (RF) circuit design, enabling frequency conversion in wireless systems while prioritising low power consumption. Recent progress in ...

If you’ve ever used an RF signal analyzer, you’re probably used to seeing displays like the spectrum graph or constellation plot. Of course, trusting the answers you get from the instrument often ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks. By ...

Today’s consumer, communication, and computer electronic devices have clocks, communication interfaces, and high-speed signal-conditioning circuits that operate at radio frequencies (RF). Providing ...

In this eGaN FET-silicon power shoot-out series article, we examine RF performance using the 200 V EPC2012 [3] eGaN FET as a starting point. The eGaN FET is optimized as a power-switching device but ...

Buzzwords like Industry 4.0, the internet of things (IoT), mobile computing, and cloud computing can currently be found in many headlines in magazines. The common theme throughout is the development ...

One of [Brian]’s hobbies is Amateur Ham radio, in which it is usually required to check that the transmitted signals are within specifications. As it isn’t safe to connect the radio’s output directly ...

[Scott] wrote in to us with his simple, but well done RF signal strength meter. As he points out in his post, sometimes an Arduino is overkill, so a Picaxe 08M was used instead. Apparently this was a ...
