Abstract
A fast start-up oscillator circuit to reduce a start-up time of a crystal oscillator is presented. The circuit contains a crystal resonator to output a first oscillation signal and a tunable RC oscillator to output a second oscillation signal. A driver is coupled between the tunable RC oscillator and the crystal resonator The driver transfers the second oscillation signal output from the tunable RC oscillator to the crystal resonator. The driver drives the crystal resonator, and a feedback circuit connected between the crystal resonator and the tunable RC oscillator to align a phase of the tunable RC oscillator with a phase of the crystal resonator based on the oscillation signal output by the crystal resonator.
