Abstract
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.
