A Wideband Low-Noise Linear LiDAR Analog Front-End Achieving 1.6-GHz Bandwidth, 2.7-pA/Hz0.5 Input-Referred Noise, and 103-dBΩ Transimpedance Gain https://sscs.ieee.org/wp-content/themes/movedo/images/empty/thumbnail.jpg 150 150 https://secure.gravatar.com/avatar/8935a7dcd6741d8e23d45bb15c1470a8?s=96&d=mm&r=g
Abstract:
This letter presents a low-noise wideband analog front-end (AFE) circuit for long-range linear LiDAR. The nMOS feedforward transimpedance amplifier with inner feedback resistor (NFFR-TIA) is proposed to extend the bandwidth to around 400 MHz and reduce the input referred noise (IRN) concurrently with high-transimpedance gain and improved stability. Two stage continuous-time …
