Abstract
An integrated circuit with a non-crystal reference clock includes: an oscillator adapted to generate and transmit an oscillator output signal, wherein the oscillator includes at least one of an inductor, a resistor, and a capacitor; a comparator adapted to receive the oscillator output signal and a calibration input signal, compare the oscillator output signal characteristics and the calibration input signal characteristics, and generate and transmit a first comparator signal in response to the comparison of the oscillator output signal and the calibration input signal; a state machine adapted to receive the first comparator signal, analyze the first comparator signal and calibrate the oscillator in response to the analysis of the first comparator signal; and a controller adapted to the receive the oscillator output signal, wherein a frequency of the oscillator output signal is utilized by the controller as a clock frequency.
