The work reports on the development of a detailed noise current model for a low-noise capacitive feedback transimpedance amplifier (TIA) in CMOS. The proposed TIA circuit implements the programmable-gain using an array of discretely controlled feedback c...

We propose a weighted singular value decomposition (WSVD) to reduce the random noise in the Rayleigh backscattering signal of the phase-sensitive optical time domain reflectometry (F-OTDR) to enhance the detection performance of the distributed vibration...

As a fully distributed sensor, the phase-sensitive optical time domain reflectometer (f-OTDR) has attracted remarkable attention in real-time vibration detection. We present a dual-channel f-OTDR (DC-f-OTDR), formed by two single-channel f-OTDRs (SC-f-OT...
