    • A self-bias operational amplifier and a small signal receiver including the same are provided. The small signal receiver according to an embodiment of the present invention includes: a first current regulating circuit which is connected between a first power source voltage (VDD) terminal and a first node (N1) and supplies a current in response to a self-bias signal; the self-biased operational amplifier which is connected between the first node and a second node, supplies the self-bias signal to a self-bias node (N3) by comparing an input signal with a reference voltage, and outputs an output signal through an output node; and a second current regulating circuit which is connected between the second node (N5) and a second power source voltage (VSS) and synchronizes the current of the second node in response to the self-bias signal. The self-bias operational amplifier includes a swing stabilization block which is connected between an input node in which the input signal is applied and the self-bias node and stabilizes the input signal which is compared with the reference voltage.
    • 提供了自偏压运算放大器和包括其的小信号接收器。 根据本发明实施例的小信号接收机包括:第一电流调节电路,连接在第一电源电压(VDD)端和第一节点(N1)之间,并响应于自偏压提供电流 信号; 连接在第一节点和第二节点之间的自偏置运算放大器通过将输入信号与参考电压进行比较来将自偏置信号提供给自偏压节点(N3),并通过 输出节点; 以及连接在第二节点(N5)和第二电源电压(VSS)之间的第二电流调节电路,并且响应于自偏置信号使第二节点的电流同步。 自偏压运算放大器包括摆动稳定块,其连接在其中施加输入信号的输入节点和自偏压节点之间,并稳定与参考电压进行比较的输入信号。
