Abstract :
A new single stage, low noise, shaper-preamplifier for optical gated signals is described. Careful layout and accurate component selection allow the use of CMOS analogue switches before signal amplification without deterioration of the noise performance of the preamplifier. With a silicon photodiode, the minimum detectable signal is less then 3000 photons for a pulse duration of 960 μs at λ=810 nm
