Clock distribution network, a semiconductor apparatus and a semiconductor system using the same

Abstract

A clock distribution network includes a global driver configured to receive a pair of clock signals to generate a pair of global clock signals, a clock transmission driver configured to amplify the pair of global clock signals to generate a pair of transmission clock signals, a first boosting circuit configured to boost voltage levels of the pair of transmission clock signals to generate a pair of first boosted clock signals, a first local driver configured to shift voltage levels of the pair of first boosted clock signals to generate a pair of first local clock signals, a second boosting circuit configured to boost voltage levels of the pair of first boosted clock signals to generate a pair of second boosted clock signals, and a second local driver configured to shift voltage levels of the pair of second boosted clock signals to generate a pair of second local clock signals.
