    • A radiation detection circuit having a multi-channel input used for radiation measurement and capable of canceling cross-talk noise generated from a logic circuit for controlling a channel and enabling low noise radiation measurement easily and precisely. The radiation detection circuit also generates an inverted signal for each of input/output signals needed for controlling its logic and cancels a noise charge generated by coupled capacity between a bonding wire (analog input side in IC package) for connecting its output to another radiation detection circuit and a bonding wire of each of input/output signals of the logic control circuit by generating an inverted noise charge with coupled capacity between the inverted signal and its output when in logic controlling, thereby suppressing the cross-talk noise generated by each of its input/output signals.
    • 一种辐射检测电路,具有用于辐射测量的多通道输入,并且能够抵消从用于控制通道的逻辑电路产生的串扰噪声并且能够容易且精确地实现低噪声辐射测量。 辐射检测电路还为控制其逻辑所需的每个输入/输出信号产生反相信号,并且消除由接合线(IC封装中的模拟输入端)之间的耦合容量产生的噪声电荷,以将其输出连接到另一辐射检测 电路和逻辑控制电路的每个输入/输出信号的接合线,通过在逻辑控制中产生反相信号与其输出之间的耦合容量的反相噪声电荷,从而抑制由其中的每一个产生的串扰噪声 输入/输出信号。
