Current starved delay element has the best features : the wider range of delay regulation, simple realization, low-power consumption
DLL circuits is used for control delay elements and lines. Ensures that the output clock signal to synchronize with a reference clock. DLL architectures is classified into three types: analog digital hybrid (with double loop) If exist, phase error between referent and output signalsa, negative feedback loop corrected delay value.
