Abstract: A method of assessing the offset on the output nodes of an amplifying channel by generating a logic signal signalling the existence of an offset of a level exceeding a window of permitted levels symmetric about the zero level, defined by a negative limit value and by a positive limit value, consists in
establishing an interval or phase of detection by applying to an input of a detection circuit a timing pulse with a certain frequency;
sensing the rising edge of the timing pulse and setting a bistable circuit;
comparing the signal on the output nodes of the amplifiers channel with said window of permitted values;
resetting said bistable circuit upon the occurrence, after said initial setting, of an output signal amplitude within said window of permitted values;
failure of said bistable circuit to reset before the end of the detection phase signalling an excessive offset.Abstract translation: 一种通过产生逻辑信号来估计放大信道的输出节点上的偏移的方法，该逻辑信号指示存在超过由负极限值定义的零电平对称的允许电平的窗口的电平的偏移，以及正的 限制值包括通过向检测电路的输入施加具有一定频率的定时脉冲来建立检测的间隔或相位; 感测定时脉冲的上升沿并设置双稳态电路; 将放大器通道的输出节点上的信号与允许值的窗口进行比较; 在所述初始设置之后，在所述允许值的窗口内的输出信号振幅发生时，重置所述双稳态电路; 所述双稳态电路的故障在检测阶段结束之前复位，发出过大的偏移。

Abstract: A method of voltage driving with a controlled current a load consists in implementing a negative feedback of the output current, measured on the collector of the output transistor of the output stage, comparing the measured output current with the input current and injecting a current difference on base node of the transistor onto which voltage driving is exerted.
