ABSTRACT:
A delay cell with a wider delay range is provided. The delay cell employs frequency dependent current source to generate the majority of the delay of the cell, while a control circuit (which is generally a current source that is controlled by a control voltage) provides additional delay. Thus, the delay cell provided here can be used to improve the performance of delay locked loops (DLLs) and other circuits.
