| description | The utility model relates to a fully differential inductance-capacitance type voltage-controlled oscillator for a decimal frequency synthesizer, which comprises a variable capacitor array, a self-biased differential output buffer and a differential tailless current source type inductance-capacitance type voltage-controlled oscillator, and the differential tailless current source type inductance-capacitance type voltage-controlled oscillator is used for providing local oscillator signals. The variable capacitor array is used for realizing a wide tuning range, and the self-biased differential output buffer is used for reducing output impedance and improving output signal swing; according to the scheme, a tailless current source technology and a second harmonic filtering technology are adopted, so that the phase noise performance of a local oscillation signal output by the decimal frequency synthesizer is improved, the oscillator in the designed scheme can work in a UHF frequency band, an oscillation signal of 1 |
