Hello everyone.

I am studing DLL at the moment.

Im trying to simulate my DLL Schematic and got curious about the 'locking time'

The DLL's sub block 'Charge Pump' generates the 'Control Volatge' which is provided into the 'Voltage Controlled Delay Line'.

I was curious about the 'Control Voltage' locking time.

Exactly when is the locking time of the 'Control Voltage' and
What is the definition of the 'Lock Time'?
