SMALL SIGNAL RECEIVER AND INTEGRATED CIRCUIT INCLUDING THE SAME

摘要

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.
