Abstract
Certain aspects of the present disclosure are directed towards a method for delay element calibration. The method generally includes: incrementing a calibration delay control signal provided to a delay element to generate an output clock signal by delaying an input clock signal; comparing, via a phase detector (PD), the input clock signal and the output clock signal to generate a PD output signal; and accumulating, via a first accumulator, the PD output signal to generate a calibration output signal.
