Abstract

See full text

The phase-lock loop (PLL) can include a variable frequency oscillator adjustable to control the phase of the output signal; a primary control subsystem including a phase detector and a connection between the output signal and the phase detector, the phase detector generating a primary control signal to adjust the variable frequency oscillator; and a secondary control subsystem having an analog-to-digital converter and a digital-to-analog converter connected in series to receive the primary control signal and generate a secondary control signal also connected to independently adjust the variable frequency oscillator.
