Patent ID: 8878609

Claim:
A differential amplifier circuit comprising: a first load between a power supply voltage terminal and a first output node; a second load between the power supply voltage terminal and a second output node; a first transistor configured to form a current path between the first output node and a common node in response to an input signal; a second transistor configured to form a current path between the second output node and the common node in response to a reference voltage; a current source configured to sink current from the common node in response to a control voltage; and a current control unit configured to generate the control voltage in response to a voltage level of the first output node and a voltage level of the second output node, wherein the current control unit comprises: a first resistor connected between the first output node and a control voltage terminal; and a second resistor connected between the second output node and the control voltage terminal, and having a resistance value higher than a resistance value of the first resistor.
