While terahertz (THz) oscillators with low phase noise have applications in radio astronomy and microscale molecular spectroscopy, they are associated with unique operational challenges based on the ...

Voltage-controlled oscillators (VCOs) are pivotal components in modern communications and signal processing, where their ability to generate a stable yet tunable signal is paramount. The performance ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

Figure 1 depicts the nature of the information provided by measuring a signal in the time domain vs. the frequency domain. Both provide insight into the content of the signal and possible approaches ...

A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...

Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But these algorithms can help ease the challenge and minimize simulation time.
