Those effects, variously known as burst noise, popcorn noise
or random telegraph noise (RTN) have become a major problem for extremely small devices, said NIST researcher Kin Cheung, the lead author of a new report (link is external) in IEEE Transactions on Electron Devices.
Like the Linear Systems LSK389, the LSK489 features a unique Monolithic Dual design construction of interleaving both JFETs on the same piece of silicon to provide exceptional matching and thermal tracking and a low-noise profile having nearly zero popcorn noise
. Lead-Free, ROHS compliant versions are available.
