The invention discloses an F-type voltage-controlled oscillation circuit and a temperature compensation method thereof, relates to the technical field of integrated circuits, used for compensating frequency deviation generated by a voltage-controlled oscillation sub-circuit due to environment temperature change. The F-type voltage-controlled oscillation circuit comprises a voltage-controlled oscillation sub-circuit and a compensation circuit. The compensation circuit comprises a current generation circuit and a voltage generation circuit, the output end of the current generation circuit is electrically connected with the first end of the voltage generation circuit and the target capacitor of the voltage-controlled oscillation sub-circuit, and the second end of the voltage generation circuit is electrically connected with the grounding end. The current generating circuit is used for providing adjusting current related to the environment temperature for the voltage generating circuit. The voltage generation cir
