DIGITAL PHASE-LOCKED LOOP SUPPLY VOLTAGE CONTROL

摘要

Some embodiments include apparatuses and methods having a digitally controlled oscillator (DCO) in a digital phase-locked loop (PLL) and a control loop. The DCO can generate an output signal having a frequency based on a value of a digital information. The control loop can adjust a value of a supply voltage of the DCO based on the value the digital information. Additional apparatuses and methods are described.
