Frequency Doubler with Duty Cycle Correction

An apparatus can implement a frequency doubler with duty cycle correction in conjunction with, for instance, a phase-locked loop (PLL) to decrease phase noise. In an example aspect, an apparatus has a frequency doubler including a signal combiner, a first signal pathway, and a second signal pathway....

Beschreibung
Zusammenfassung:	An apparatus can implement a frequency doubler with duty cycle correction in conjunction with, for instance, a phase-locked loop (PLL) to decrease phase noise. In an example aspect, an apparatus has a frequency doubler including a signal combiner, a first signal pathway, and a second signal pathway. The frequency doubler also includes a doubler input node and a doubler output node. The signal combiner is coupled to the doubler output node. The first signal pathway is coupled between the doubler input node and the signal combiner and includes a first adjustable delay cell. The second signal pathway is also coupled between the doubler input node and the signal combiner and includes a second adjustable delay cell.
