Laser Pulse Timing Detector

A laser pulse timing detector has been designed. The circuit consists of a low-noise transimpedance amplifier channel with gain control and a timing detector. The measured bandwidth of the amplifier channel is 10 MHz, transimpedance 340 k¿ - 2.7 M¿ and input referred noise 0.9pA/¿Hz. The walk error of the timing detector is +/- 50ps, when its input signal amplitude varies from 150 mV to 2.5 V.
