DLL-based 4-phase duty-cycle and phase correction circuit for high frequency clock tree

In high-speed data transmission applications such as double data rate memory and double sampling ADCs, clock generation and distribution circuits must provide the clocks with precise duty cycle of 50% and sufficient timing margin. The proposed DLL-based 4-phase duty-cycle and phase correction circui...
