摘要:
The present invention relates to a radiation counting apparatus, a noise estimation method, a program, and a recording medium storing the same, for adjusting a signal delay and a voltage offset. A CDM unit for outputting a second signal having an input terminal connected to an output terminal of the preamplifier, a first signal input and a second signal having at least one of a signal delay and an offset adjustment applied to a first signal; And a CDS unit having an input terminal connected to the output terminal of the CDM unit and outputting a third signal generated in accordance with a difference value between the first signal and the second signal at an output terminal and the third signal includes a first signal or a second signal Has a magnitude in proportion to the amount of change of the first signal or the second signal and has a base voltage which is an arbitrary voltage when the difference between the first signal and the second signal is inverted and the CDM unit includes an RC circuit and an amplifier And derives the difference between the starting point and the maximum point of the first signal based on the voltage of the third signal and adjusts the signal delay of the second signal and the offset of the base voltage to optimize the noise of the third signal A radiation detecting device for detecting a radiation, According to this, there is an effect that it is possible to provide a radiation counting apparatus capable of measuring a radiation coefficient and energy information with a small area and a simple structure.본 발명은 신호 지연 및 전압 오프셋(offset) 조절을 위한 방사선 계수 장치, 노이즈 최적화 방법, 프로그램 및 이를 저장한 기록매체에 관한 것이다. 이를 위하여 입력단이 전치 증폭기의 출력단에 연결되고, 제1신호가 입력되며, 제1신호에 신호 지연 및 오프셋 조정 중 적어도 하나를 적용한 제2신호를 출력단에서 출력하는 CDM부; 입력단이 CDM부의 출력단과 연결되고, 제1신호와 제2신호의 차이값에 따라 생성되는 제3신호를 출력단에서 출력하는 CDS부;를 포함하고, 제3신호는, 제1신호 또는 제2신호가 입력되는 때에는 제1신호 또는 제2신호의 변화량에 비례하는 크기를 가지며, 제1신호와 제2신호의 차이가 반전되는 때에는 임의의 전압인 베이스 전압을 갖고, CDM부는 RC회로 및 앰프를 포함하는 전역 통과 필터로 구성되며, 제3신호의 전압을 토대로 제1신호의 시작점과 최대점의
