Abstract: A voltage-controlled oscillator is disclosed. The voltage-controlled oscillator includes an inverter circuit configured to output an oscillation signal. The first inverter circuit includes a complementary transistor pair and a transistor string. The complementary transistor pair includes a first switch transistor and a second switch transistor. The second switch transistor is connected to the first switch transistor, in which a first terminal of the second switch transistor is connected to a second terminal of the first switch transistor. The first delaying unit includes at least one delaying transistor. A first terminal of the at least one delaying transistor is connected to a control terminal of the second switch transistor. A second terminal of the at least one delaying transistor is connected to a control terminal of the first switch transistor. A control terminal of the at least one delaying transistor is configured to receive a voltage control signal.
