Circuit arrangement and method for charge integration

A circuit arrangement for charge integration comprises an input (1) for applying a signal representative of a charge pulse, an output (2) for providing an integrated signal, and an integration circuit (3) connected between the input (1) and the output (2), comprising a resistive circuit (5) and a capacitor (6), and having an RC time constant, the RC time constant is a function of the resistive circuit (5) and the capacitor (6). The circuit arrangement further comprises a feedback control circuit (7) connected at its input to the output (2) of the circuit arrangement and providing at its output a control signal wherein at least one of the resistive circuit (5) and the capacitor (6) has a variable value dependent on the control signal. 一种用于电荷积分的电路装置包括输入(1)、输出(2)和积分电路(3)，该输入用于施加表示电荷脉冲的信号，该输出用于提供积分信号，该积分电路连接在输入(1)与输出(2)之间，包括电阻电路(5)和电容器(6)，并且具有RC时间常数，该RC时间常数是电阻电路(5)和电容器(6)的函数。电路装置还包括反馈控制电路(7)，该反馈控制电路在其输入处连接到电路装置的输出(2)并且在其输出处提供控制信号，其中，电阻电路(5)和电容器(6)中的至少一个具有取决于控制信号的可变值。
