METHOD AND SYSTEM FOR OPEN LOOP COMPENSATION OF DELAY VARIATIONS IN A DELAY LINE |
摘要 |
The present invention provides a method and system for open loop compensation of delay variations in a delay line. The method includes sensing the Process, Voltage, Temperature (PVT) variations in the delay line using a sensing circuit. A first and second sensitive current are generated based on the PVT variations. The first and second sensitive currents are mirrored currents from the sensing circuit. Then, a first compensation current is generated based on the first sensitive current and a first summing current. The first summing current is a reference current independent of the PVT variations. Further, the first compensation current is mirrored as a second summing current and a second compensation current is generated from the second sensitive current and the second summing current. The second compensation current compensates the delay variations and has a sensitivity based on the sensitivities of the first and second sensitive currents. |
