Apparatus, methods and articles of manufacture for dynamic differential delay correction

A method for dynamically correcting a signal being processed, said method comprising the steps of:

• processing an amplitude aspect and a phase aspect of said signal along an amplitude and a phase paths, respectively;
• quantizing said phase aspect of said signal to generate an actual phase value;
• comparing said actual phase value with an expected phase value to determine any delay in an analog portion of said phase path in relation to said amplitude path;
• generating a correction signal based upon said comparison;
• and
• using said correction signal to adjust said amplitude aspect of said signal.

An apparatus for dynamically correcting a signal comprising:

• at least one signal path for processing the phase of said signal;
• at least one separate signal path for processing the amplitude of said signal;
• a quantizer for generating a value of said phase along said one signal path;
• a digital phase locked loop for comparing said value with an expected value to determine any delay in an analog portion of said one signal path relative to said separate signal path, and to generate a correction signal based upon said comparison;
• and
• a bank of pipeline registers for adjusting said separate signal path.
