Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

The need for high-frequency semiconductor devices is surging, fueled by growing demand for advanced telecommunications, faster sensors, and increasingly autonomous vehicles. The advent of ...

The injection-locked frequency divider (ILFD) is a pivotal building block in modern radio frequency (RF) and mixed-signal systems. By utilising the phenomenon of injection locking, these dividers ...

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 ...

Terahertz devices will greatly increase the speed at which data can be transferred and processed. In this study, researchers developed a novel strategy to convert the frequency of a terahertz wave ...

The previous column in this series discussed driver and layout considerations to improve the performance achievable with eGaN FETs. In this installment the optimum layout will be implemented in a high ...
