Abstract:
A voltage controlled oscillator includes a resonant circuit including one or more transformers and a plurality of variable capacitor circuits connected in parallel to the one or more transformers and generating a plurality of oscillation signals having multiple phases, and a negative resistance circuit including a plurality of transistors cross-coupled via the one or more transformers and generating negative resistance for maintaining the oscillation of the resonant circuit.
