  • Apparatus, system and method for controlling temperature and power supply voltage drift in a digital phase locked loop
    Patent number: 9484938
    Abstract: Described herein are apparatus, system, and method for controlling temperature drift and/or voltage supply drift in a digital phase locked loop (DPLL). The apparatus comprises a DPLL including a digital filter to generate a fine code for controlling a frequency of an output signal of a digital controlled oscillator (DCO) of the DPLL; a logic unit to monitor the fine code and to generate a compensation signal based on the fine code; and a voltage adjustment unit to update a power supply level to the DCO based on the compensation signal, wherein the updated power supply level to cause the digital filter to generate the fine code near the middle of an entire range of the fine code across various temperatures, and wherein the digital filter to generate the fine code near the middle of the entire range across power supply drift.
