摘要:
Provided is a voltage controlled oscillator having a new type of a resonator and a negative resistance part capable of finely tuning negative resistance. Thus, the voltage controlled oscillator has an excellent quality factor characteristic and can finely tune the negative resistance even after its fabrication is completed. The voltage controlled oscillator having an active element includes: a resonating unit for generating an oscillation frequency according to a resonance capacitance; a frequency tuning unit, connected to a source terminal of the active element, for tuning the oscillation frequency; and a negative resistance adjusting unit, connected to the frequency tuning unit, for generating a negative resistance to adjust the oscillation frequency, the negative resistance adjusting unit including a varactor diode for finely adjusting the negative resistance.
