The traditional multi-channel pulse amplitude analyzer based on single chip computer with low integration is difficult to design or update.A multi-channel pulse amplitude analyzer based on 32 bits microcontroller S3c2440 is proposed in this paper.The major circuit components are described including the pulse discriminator circuit,peak detector circuit,logic control circuit and A/D converting circuit.The discriminator circuit can remove low energy noise by setting a Threshold Voltage.The peak detector circuit can detect when the peak voltage come,and expands the time of peak voltage to adapt to the A/D convertor.The control circuit can precisely control the working time sequence of the whole system.The A/D convertor converts the Analog signal into digital signal.The experimental results show that the instrument can be used in practical fields for its lower INL/DNL,high-speed and stable performance.

Key words: multi channel pulse amplitude analyze;S3C2440;peak detector
