ABSTRACT:
There is provided a differential amplifier including: an output terminal through which an output voltage is outputted in response to an input voltage; a first inverter-type input unit connected between a first node and a second node to receive the input voltage; a second inverter-type input unit connected between a third node and a fourth node and receiving a reference voltage and having an output node connected to the output terminal; a circuit biased by an output of the first input unit and configuring a negative feedback loop together with the first input unit; an amplifying unit biased by the output of the first input unit to amplify the output of the first input unit; and a switching unit connected between the first node and the third node and between the second node and the fourth node in response to a voltage level of the output terminal.
