Embodiment Construction
[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0046] Such as figure 1 and figure 2 As shown, a high-frequency broadband voltage-controlled oscillator, including:
[0047] The input buffer unit 1 is connected to the control voltage and transmits the voltage signal to the resonance unit 2;
[0048] The resonant unit 2 is used to generate an oscillating signal according to the voltage signal, and transmit the oscillating signal to the output buffer unit 3;
[0049] The output buffer unit 3 is used to buffer the oscillating signal and output the oscillating signal;
[0050] The negative resistance unit 4 is used to generate negative resistance, and use the energy generated by the negative resistance to compensate the loss of the resonance unit 2;
[0051] The ...
