Abstract:
Provided are a differential amplifier circuit and a method of generating a bias voltage in a differential amplifier circuit. The differential amplifier circuit is turned on or turned off in response to an input voltage and includes a differential amplifier and a bias circuit. The bias circuit provides a first bias voltage to a gate of a pull-down transistor included in the differential amplifier when the differential amplifier is turned on and provides second bias voltage which is lower than the first bias voltage to the gate of the pull-down transistor when the differential amplifier is turned off.
