An oscillation circuit induces a first inverter, a second inverter, a first inductive load, a second inductive load and a capacitive load. A first inverter and a second inverter receive a first signal and a second signal, and invert the first and the second signal to output a first inverted signal and a second inverted signal respectively. An output end of the first inverter is electrically connected to a first inductive load, and an output end of the second inverter is electrically connected to a second inductive load. Further, a capacitive load is electrically connected to the output end of the first inverter and the output end of the second inverter, so as to receive the first and the second inverted signal respectively. The capacitance of the capacitive load changes with a control signal.
