The purpose of this project is to implement a device that can detect the presence of gamma photon radiation. The detection circuit can be divided into a few small sub functions that consist of signal sensor, amplifier and comparator. That signal will be detected by using PIN photodiode. Detected signal is then being amplified by using the low noise amplifier. The low noise amplifier being chosen in the system due to the incoming signal might be very small. Therefore, the probability that the signal noise affecting the system can be minimize. After the pre-amplifying process, the final stage is to compare the incoming signal with initial reference voltage. The design circuit produces high pulse if the incoming signals match with the system specification. The circuit for the gamma photon radiation detector is being tested using PSPICE computer simulation program and actual setup of the circuit. The result between the both approaches is then being compared and discuss.
