Abstract
A buffer circuit includes an amplification unit configured to amplify and output a difference between an input signal and a reference voltage; and a driver configured to drive an output node in response to the output of the amplification unit and be controlled in at least one of a pull-up driving strength and a pull-down driving strength at the output node in response to the reference voltage.
Claims16
A buffer circuit comprising:
- an amplification unit configured to amplify a difference between an input signal and a reference voltage and output the amplified difference as an output of the amplification unit;
- and
- a driver configured to drive an output node in response to the output of the amplification unit and be controlled in at least one of a pull-up driving strength and a pull-down driving strength at the output node in response to the reference voltage.
A buffer circuit comprising:
- an amplification unit configured to amplify a difference between an input signal and a reference voltage and output the amplified difference as an output of the amplification unit;
- a driving unit configured to pull-up drive or pull-down drive an output node in response to the output of the amplification unit;
- and
- a driving strength control unit configured to control at least one of a pull-up driving strength and a pull-down driving strength of the driving unit at the output node in response to the reference voltage.
