摘要: 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 noise performance preamplifier. With a silicon photodiode, minimum detectable less then 3000 photons pulse duration 960 mu s at lambda =810 nm.
