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 ...

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 ...

The system in Figure 2 uses the ADF4372 PLL (see Figure 5), a wideband synthesizer with integrated VCO, that allows the implementation of fractional-N or integer-N frequency synthesizers when used ...

Finally, the DC offset introduced by the RF signal is measured by a digital multimeter. Note that a low-pass filter is used between the amplifier and the multimeter to prevent potential errors caused ...

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 ...
