Abstract :
A receiver channel consisting of a low-noise transimpedance preamplifier, variable R-2R ladder attenuator, voltage amplifier, peak detector, r.m.s. noise meter and highpass/lowpass timing detector has been designed for a laser rangefinding device. The measured bandwidth of the amplifier channel is 10 MHz, transimpedance 340 kΩ to 2.7 MΩ and input referred noise 0.9 pA/√Hz. The walk error of the timing detector is +/- 50 ps, when its input signal amplitude varies from 150 mV to 2.5 V. Measurement results show that a dm-level distance measurement accuracy has been realized using integrated ASICs
