Embodiment Construction
[0025] Such as figure 2 Shown is a circuit structure diagram of a voltage-controlled oscillator according to an embodiment of the present invention. The voltage-controlled oscillator in the embodiment of the present invention includes: a bipolar voltage-controlled oscillator unit 1 and output buffer units 2a and 2b. The bipolar voltage-controlled oscillator unit 1 is a fully differential structure, which can output a pair of differential pairs of the first oscillating signal; the output buffer unit 2a and the output buffer unit 2b are symmetrically arranged, and can respectively adjust the differential pair of the first oscillating signal. output after buffering.
[0026] The bipolar voltage controlled oscillator unit 1 includes an LC resonant circuit module and a negative resistance circuit module.
[0027] The LC resonant circuit module is used to generate a first oscillating signal with a required oscillating frequency, and the LC resonant circuit module includes two fir...
