Abstract: We previously derived the power spectral density (PSD) of thermal flux fluctuations at low frequencies for a thermal conductor under non-equilibrium conditions, which is relevant for device ...

Are you one of those people who can’t drop off to sleep if it’s “too quiet”? If so, you’re not alone. According to a 2023 survey of UK participants, 50% of people listen to some kind of noise to help ...

Everyone thinks about food sometimes, whether it’s deciding what to eat for breakfast or what to order at a restaurant. But when these thoughts become so pervasive that we constantly think about ...

This project made me feel a kind of kinship with Diogenes, although I was searching for the item described in the title rather than for an honest man. Figure 1 “Diogenes Looking for an Honest Man,” a ...

A small British software startup called Spectral Compute Ltd. believes it has what it takes to break Nvidia Corp.’s stranglehold on artificial intelligence data centers after raising $6 million in ...

Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...

Abstract: We derive the average noise voltage spectral density at the output of a one-port network comprising inductors, capacitors, resistors, and periodically-operated switches. The derivation ...
