Multi-band voltage controlled oscillator circuit |
摘要 |
Disclosed is a multi-band voltage controlled oscillator circuit comprising a resonant circuit including at least one varactor, at least one capacitor and at least one inductor operated in response to a control voltage, the resonant circuit having a resonance frequency determined according to capacitances of the varactor and capacitor and an inductance of the inductor. The multi-band voltage controlled oscillator circuit further comprises at least one band selection circuit for adjusting the resonance frequency in response to a band selection signal, the band selection circuit including at least one capacitor connected in parallel to the resonant circuit, and a switching element for turning on/off the capacitor in response to the band selection signal. |
