Abstract
A buffer circuit includes a first buffer configured to operate at an external power voltage, generate first and second buffer signals by comparing an input signal with a reference voltage, and control potential levels of the first and second buffer signals in response to a common mode feedback voltage; a second buffer configured to operate at an internal power voltage and generate an output signal in response to the first and second buffer signals; and a replica circuit configured to generate the common mode feedback voltage to be less than the internal power voltage.
