ABSTRACT:
A clock buffer circuit of a semiconductor device is disclosed which receives an external clock signal and generates an internal clock signal with no duty distortion. The clock buffer circuit includes a first clock buffer for receiving and buffering a normal-phase clock signal, a second clock buffer for receiving and buffering a reverse-phase clock signal, and an internal clock generator for generating an internal clock signal in response to output signals from the first and second clock buffers.
