Abstract: A temperature compensated, auto tunable, frequency locked loop oscillator includes, in one embodiment, an oscillator configured to generate a clock-signal with a frequency fclk based on a control voltage vc, and a frequency-to-voltage (f/v) converter coupled to the oscillator, which is configured to generate a first voltage vfb with a magnitude based on frequency fclk. A controller is also included and coupled between the oscillator and the f/v converter. The controller is configured to control the magnitude of the control voltage vc based on the first voltage vfb.
