Abstract
A semiconductor device and method of generating clock signals where a phase lock loop (PLL), or a delay lock loop (DLL), comprises a duty cycle correction circuit (DCC) having a shared charge pump and a plurality of amplification parts. The plurality of amplification parts generate internal clock signals. The shared charge pump adjusts voltage level of control signal (VC) in response to the internal clock signals and provides the control signal VC to each of the amplification parts.
