Abstract
A crystal oscillator including a feedback circuit, and a reference clock generating circuit including the crystal oscillator. The crystal oscillator is configured to generate an oscillating signal based on a natural frequency of a crystal. The crystal oscillator may include: a current generating circuit connected to a first node having a first voltage and a second node having a second voltage, and configured to output a first current to the second node; a feedback circuit connected to the generating circuit via the first and second nodes and configured to adjust a level of the second voltage by controlling a level of the first voltage; and a crystal circuit connected to the second node and configured to generate the oscillating signal based on the second voltage.
