This paper presents a transimpedance-to-noise optimization approach for design of a resistive shunt-feedback TIA. This optimization offers an enhancement in the transimpedance and a noise performance very close to the theoretical minimum noise of the

A newly devised radical-based strategy enabled coupling between multiply oxygenated α-alkoxyacyl tellurides and 2-hydroxybenzaldehyde derivatives. A reagent combination of Et3 B, Et2 AlCl, and O2 promoted the formation of the α-alkoxy carbon radica

Object detection plays an important role in the field of remote sensing imagery analysis. The most challenging issues in advancing this task are the large variation in object scales and the arbitrary orientation of objects. In this paper, we build a

In this letter, a low cost, compact, and systematic method for generating a short pulse and efficiently delivering it to low impedance loads is proposed. The load can be a resistive on-chip or off-chip load, an antenna, or another stage such as a pow

Frequency scanning interferometry (FSI) can achieve high-precision absolute distance measurement. Here, a new double sideband frequency scanning interferometry (DSB-FSI) system is proposed, which enables long-range, high-precision measurements. Furth

Synthetic aperture ladar (SAL) is analogous to the synthetic aperture radar (SAR) but works at wavelength 104-5 times shorter. SAL has the potential for much finer resolution than SAR. Due to the shorter wavelength used for SAL, the platform vibratio

In this manuscript, an Inverse Synthetic Aperture LADAR (ISAL) system at 1.55 μm wavelength is introduced. We have recently completed an imaging experiment on real target 1.1 km away from laser radar by using the system and obtained a series of imag
