Abstract Fast Pre-amplifier is designed for Semiautomatic twilight photometer, used for aerosol measurements over Kolhapur (16°42′N, 74°14′E). This amplifier is designed and developed by connecting 10 single IC amplifiers in parallel. The efficiency of the system is increased by adopting multiple pre-amplifier configuration which improves signal to noise ratio by factor of 10 and this fact is responsible for measuring low level intensity by photometer. Therefore the duration of operation of the system has been increased to 90 min as compared to 45 min obtained by earlier system. As a result the system now can yield a reasonable qualitative picture of the vertical distribution of aerosols from about 6 km to a maximum of 350 km. Some noticeable features of the Fast Pre-amplifier are high speed, high gain, high slew tare and low noise etc. Thus the sensitivity of the system is improved a lot. KEY WORDS: Fast Pre-amplifier, high gain, low noise, sensitivity
