Accurate Characterization for Continuous-Time Linear Equalization in CMOS Optical Receivers
IEEE Access, 2022 Recently published CMOS optical receivers consist of a limited-bandwidth first-stage transimpedance amplifier (TIA) followed by an equalizer. Limiting the TIA’s bandwidth improves the gain and reduces the noise but introduces a significant inter ...

Improving temporal resolution of ultrafast electron diffraction by eliminating arrival time jitter induced by radiofrequency bunch compression cavities [PDF]
, 2017 The temporal resolution of sub-relativistic ultrafast electron diffraction (UED) is generally limited by radio frequency (RF) phase and amplitude jitter of the RF lenses that are used to compress the electron pulses.

Practical Limits on Nanosatellite Telescope Pointing: The Impact of Disturbances and Photon Noise
Frontiers in Astronomy and Space Sciences, 2021 Accurate and stable spacecraft pointing is a requirement of many astronomical observations. Pointing particularly challenges nanosatellites because of an unfavorable surface area–to-mass ratio and a proportionally large volume required for even the ...
